2011-05-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java:
	  New. An OutGenerator for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/model/WQDay.java: New. A
	  model class to store necessary data for creating W and Q facets of a
	  duration curve. This model stores W, Q and Days.

	* src/main/java/de/intevation/flys/artifacts/model/MainValuesFactory.java:
	  Added a function to retrieve tuples of (day, q) based on a given gauge -
	  these tuples are necessary for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  methods to compute and retrieve the data necessary for creating duration
	  curves.

	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java:
	  Bugfix: improved the access to the location array (avoid
	  NullPointerException).

	* doc/conf/conf.xml: Registered the new OutGenerator for duration curves.

2011-05-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* contrib/visualize-transitions.xsl: State quoting was done wrong.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Enhanced the transition model to reach the
	  final state for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java:
	  New. This state should be reached to just insert an array of locations.

	* src/main/java/de/intevation/flys/artifacts/states/DurationCurveState.java:
	  New. This state is reached if the duration curve calculation is
	  selected.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Adjusted
	  getDistance() so that it takes care on inserted locations - not just
	  inserted ranges.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
	  Flush/persist caches at program exists.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Commented out too eloquent debug output.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Uses the methods of FLYSArtifact to retrieve the necessary information
	  rivername and selected distance.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Added interpolateW method to take reference to result ws array
	  as an argument to avoid expensive array allocations in km iterating
	  loops.

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
	  Added a constructor to create backing trove datastructure
	  with the right capacity.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Move allocation of result ws out of km loop.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Added two further data items in the WQ
	  selection state. Those items are necessary to store the information
	  about the selected mode (range/single selection) and  the values of the
	  single selection.

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java: If
	  there is no value for a data item, this item is not written into the
	  static DESCRIBE part.

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java,
	  src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java:
	  Renamed the method to validate upper and lower values.

	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java: This
	  state can now handle values inserted in the single selection. Therefore,
	  new validate methods has been added.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
	  methods getWs() and getWs() take care on the values inserted in the
	  single insert mode of the client which enables the user to insert single
	  W and Q.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Repaired getQForW() by calculating indices on right dimension.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New
	  methods for retrieving selected W values (getWs()).

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  method for retrieving waterlevel data takes care on selected Ws, now.
	  The selected Ws are transformed using the DischargeTables.getQForW()
	  into Q values.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Removed an unused parameter 'result' of getQForW().

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Removed
	  the getDataset() method and replaced it with a addDataset() method.
	  On this way, concrete subclasses of this OutGenerator can have multiple
	  datasets (e.g. different datasets for W and Q). This abstract method is
	  called after the chart generation is finished.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Both classes implement the addDataset() method. The
	  LongitudinalSectionGenerator has already multiple datasets for W and Q.
	  Both are added to the chart - both have an own range axis.

2011-05-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Use the cache for the wst value table if configured.

	* doc/conf/cache.xml: Choose a more precise name for the 
	  wst value table cache.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* pom.xml: Added dependency to Ehcache. Apache 2.0 license.

	* doc/conf/conf.xml: Added configuration of ehcache.

	* doc/conf/cache.xml: New. Cache configurations.

	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
	  New. Factory to access caches.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Forgot to add.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  New. Given a database connection and a XML template it generates
	  an output with meta data about the database.

	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
	  New. Holds prepared statements optimized to be run in the stack of
	  contextes.

	* src/main/java/de/intevation/flys/artifacts/services/meta/StackFrames.java:
	  New. Model to hold a hierarchical scope of variables.

	* src/main/java/de/intevation/flys/artifacts/services/meta/ResultData.java:
	  New. Stores data set fetched from a sql select to be iterated in
	  a context.

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java,
	  src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Removed superfluous imports.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/conf/conf.xml: Added meta data service.

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Stub for the meta data service.

	* src/main/resources/metadata/template.xml: Initial template for
	  the meta data service.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Bugfix: Now, curves for Q values are drawn into a longitudinal section
	  chart as well. Therefore, it was necessary to change the datastructure
	  of the inner class ThemeList that stores all themes included in a chart
	  in an ordered list (stored in a java.util.Vector now).

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: New. An
	  abstract base class for ChartGenerators that create XY charts.

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Sourced the generate() method out to the XYChartGenerator.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Implemented the methods to add W and Q facets to the chart.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Improved
	  the calculation of the step with for ranges.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: Added a
	  method that returns the number of elements stored in the data pool.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
	  Added a get() method which takes destination array as an
	  argument.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: Changed the
	  data structure to store w, q and kms values from List<Double> to
	  TDoubleArrayList which stores native double values instead of big
	  Double values.

	* pom.xml: Added the GNU Trove dependency.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/OutGenerator.java: Added the
	  name a the requested facet to doOut(). Concrete generators should just
	  create output for this facet now.

	* src/main/java/de/intevation/flys/exports/ChartGenerator.java,
	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Adapted the method signature of doOut().

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted the method call of OutGenerator.doOut().

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/themes.xml: Added mappings for the facets
	  longitudinal.section.w and longitudinal.section.q.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added some
	  methods to retrieve necessary information for computing the data of a
	  waterlevel.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  methods to compute and retrieve the data of a waterlevel computation.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: New. This
	  model class represents a pool of data triples that consist of W, Q and
	  Kms information. This class might be used to compute data for creating
	  longitudinal section curves (which are based on those W, Q and Kms
	  values).

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Bugfix: Removed endless loop and a bug while iterating over Hibernate
	  results.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  New. An OutGenerator that creates longitudinal section curves.

	  NOTE: This is just the stub - the out creation needs to be implemented!

	* doc/conf/conf.xml: Added the LongitudinalSectionGenerator.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Bugfix: Added missing <output-generators> section.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WaterlevelState.java: New.
	  This state should be reached if the 'calc.surface.curve' calculation
	  method has been chosen.

	* doc/conf/artifacts/winfo.xml: Modified a transition and added the
	  WaterlevelState. This state is reached if the 'calc.surface.curve'
	  calculation method has been chosen. It currently has 1 output - a
	  longitudinal section that is not implemented yet!

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/transitions/ValueCompareTransition.java:
	  New. This transition is valid if the a data object of the current
	  artifact equals/notequals a configured value in the transition model.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Bugfixes:
	  - Adapted the parameters of the isStateReachable() call - added the
	    artifact and the current state.
	  - Append the outputs of a current state if the state is filled with
	    valid data.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java:
	  Added the missing init() method that has been introduced in the
	  interface some commits ealier.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  Call init() after a Transition has been created.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java:
	  Bugfix: Introduced a <art:outputs> node in the attribute document of a
	  Collection that contains further <art:output> nodes - instead of having
	  multiple <art:output> nodes at toplevel of the document.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted the XPath to retrieve the outputs in the attribute document of a
	  Collection.

2011-04-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* contrib/visualize-transitions.xsl: Added to create a 
	  Graphviz digraph out of the config.xml. Usage:

	  $ xsltproc --stringparam base-dir ../doc/conf/ \
	    contrib/visualize-transitions.xsl \
	    doc/conf/conf.xml > transitions.dot

	  $ dot -Tsvg -o transitions.svg transitions.dot

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:
	  If no data has been inserted so far, an IllegalArgumentException is
	  thrown.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java::
	  A lot of new methods to retrieve the theme of a facet - used while
	  creating the output of a facet/artifact. If a facet has no theme yet, it
	  is initialized.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/AttributeParser.java,
	  src/main/java/de/intevation/flys/collections/OutputParser.java: Removed
	  useless imports.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: New. An
	  abstract OutGenerator that might be used to create chart output. Some
	  basic things that are equal in all charts should be done here!

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  This OutGenerator no longer implements the OutGenerator directly, but it
	  extends the ChartGenerator now.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Restructured the out() operation of a collection: Now, we collect a list
	  of artifacts/facets and use this for the OutGenerator. Its doOut()
	  method gets the attribute of an artifact - the position and the active
	  state is managed by the Collection itself.

2011-04-26  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java: New.
	  a specialized facet that stores information about its position and its
	  state (active/inactive) in an output of a collection.

	* src/main/java/de/intevation/flys/collections/AttributeParser.java: New.
	  This parser takes the attributes (XML) of a collection and extracts the
	  contained outputs with its facets. The result is a Map<String, Output>.

	* src/main/java/de/intevation/flys/collections/OutputParser.java: New.
	  This parser is used to query the artifact's DESCRIBE and to extract the
	  supported outputs. The result is a Map<String, Output>.

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: New.
	  This writer merges the outputs contained in an attribute of a collection
	  with the outputs of a collection's artifacts.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  The attributes of a collection are written into its DESCRIBE document
	  now. The OutputParser and AttributeParser are used to read the supported
	  attributes by the collection and its artifacts - the AttributeWriter is
	  used to merge both attributes and create a final attribute document.

2011-04-26  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java,
	  src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The facet-2-theme mappings are initialized at startup and stored in the
	  FLYSContext.

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Added a
	  function that retrieves a theme from FLYSContext based on its name.

2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Corrected a silly c&p mistake.

2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/math/BackJumpCorrector.java:

	  Implementation of the "Ruecksprungkorrektur" to be done in
	  "W fuer angepassten Abflusslaengschnitt".

	  All tests show the expected results. In some corner cases the
	  algorithm described in the "Anwenderhandbuch" chapter 3.3.4.3 "Korrektur"
	  has some definition shortcomings:

	  a - What should happend when you cannot find point 2 because
	      you cannot step back one quarter from point 3 because there
	      is no data there any more (river too short in this direction)?
	      The implemented algorithm raises point 3' only to an
	      according factor. E.g. If you can step back the whole quarter
	      distance the elevation is the full quarter. If you can
	      step back only the half of the quarter the elevation is
	      only an eighth.

	  b - If the water heights between point 2 and 3 are constant then
	      the algorithm will produce a spline interpolation that
	      lowers those values. Is this intended?

	  For real data the back jumps are expected to be more in the middle
	  of the distance ranges so the corner cases are maybe not so
	  important.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Removed superfluous import.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Removed debug
	  code that has been commited by accident.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/themes.xml: New. A first small theme configuration.

	* doc/conf/conf.xml: Added a link to the theme configuration.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
	  Defined a key that is used to store a themes map in the FLYSContext.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The theme configuration is read at startup and the themes are stores in
	  the FLYSContext.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/themes/Theme.java,
	  src/main/java/de/intevation/flys/themes/DefaultTheme.java:
	  New. The interface and its default implementation that represents themes
	  used to style charts and maps.

	* src/main/java/de/intevation/flys/themes/ThemeField.java,
	  src/main/java/de/intevation/flys/themes/DefaultThemeField.java:
	  New. The interface and its default implementation that represents fields
	  in themes. A theme might be "Lines" and one of its field might be
	  "Color" or "Size".

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: A factory
	  that creates new themes based on a theme configuration.

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Implementation of "Abflusskurve/Abflusstafel" calculation.

	  Added method interpolateWQ() which takes an km and results in a
	  tuple of two double arrays containing the w/q values interpolated
	  between the surrounding w/q values of the table.
	  w values are interpolated linear, q values with a cubic spline.

	  Drawing w over q gives you the discharge table at the given km.

	  !!! This code needs testing !!!

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* pom.xml: Added dependency to Apache Commons Math 2.2 (Apache License 2.0)

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Fix problem when sorting by q (copied w instead of q).

2011-04-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Fixed broken HQL statement.

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  add a method interpolateW() which takes an array of
	  q values and returns an equal sized array of w values.
	  This is essentially the "Wasserstand/Wasserspiegellagen" calculation
	  of desktop FLYS.

	  If you want to do a calculation with given w values you have
	  to convert the w values with DischargeTables.getQForW() first.

	  !!! This code needs heavy testing !!!

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  We need a getQForW() method and not getWForQ() because when
	  doing a "Wasserstand/Wasserspiegellagen" calculation with given
	  w values these values need to be translated to q values with
	  the master discharge table.

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Sorting of q values was done wrong.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/AnnotationsFactory.java:
	  Ordered the list of annotations returned by this factory based on its
	  range.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MainValuesService.java:
	  New. This service returns an XML document that includes the main values
	  of a gauge based on a river name, a start and an end point.

	* doc/conf/conf.xml: Registered the MainValuesService.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/MainValuesFactory.java:
	  A factory that provides methods to return MainValues.

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Added static method getWForQ() to interpolate a w value for

	  It should return true, if the data of the State is fine, otherwise it
	  should raise an exception.

	  NOTE: The exceptions are not translated in the server but in the client!

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java: New.
	  This abstract class exists to provide some methods for handling ranges.
	  Currently, there is a method that validates a given range based on
	  min/max values.

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:

2011-04-12  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Bugfix:
	  States are filled with data before they describe themself.

	  the code to create discharge curves. It has moved to the
	  DischargeCurveGenerator which now does this work.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/**/*.java: Removed trailing whitespace.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Introduced a 'scale' parameter in the getValues() method.

	  Removed needless import.

2011-03-24  Ingo Weinzierl <ingo@intevation.de>

	* src/main/resources/messages_de_DE.properties: Added a german resource
	  bundle to avoid exceptions in the flys artifacts. Sometimes, the
	  Resources class is not able to find a 'de_DE' bundle and throws an
	  exception. This is really strange, because it should use the 'de' bundle
	  in that case, but it doesn't.

2011-03-23  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  some code to append the output modes of previous states to the DESCRIBE

	  New. A state for the location/distance selection of the WINFO
	  parameterization.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a new method getUIProvider() that might be overriden by concreted
	  subclasses that should be rendered with a specific UIProvider.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  The static UI part is created by the previous states now. This makes it
	  possible to group the data objects (which is necessary to group the
	  objects in the ui).

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a describeStatic() method that creates a node that contains the

	* src/main/java/de/intevation/flys/artifacts/states/CalculationSelect.java:
	  New. The state for choosing the calculation mode.

	* src/main/resources/messages.properties,

	  src/main/resources/messages_de.properties: Added i18n strings for the
	  calculation mode state.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  New. This is the base state for the FLYS application. It provides a

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
	  operations feed() and advance() return the description of the artifact
	  using the describe() operation. This avoids additional server round trips
	  in the client - the clients gets to know about the new state of the
	  artifact immediately.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented a part (step forward) of the advance operation.

	* TODO: Implement Step-Back in advance operation.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Implemented the abstract method getName(). It returns the constant
	  'winfo' string.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented the feed action. The data of an incoming feed() operation is
	  stored in StateData objects that are saved in a map in the artifact.

	  NOTE: There is no input validation and no i18n of error messages (see
	  TODO).

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* TODO: This file contains some open points that need to be done.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New. This
	  artifact serves as the default artifact for the FLYS application.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: This
	  artifact now inherits from FLYSArtifact. Furthermore, there is one big
	  change: we don't store the State objects itself in the artifact, but
	  just the identifier of those. This makes the artifact smaller and more
	  compatible agains previous versions of the software.

2011-03-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
	  New. This service will retrieve a list of provided rivers.

	* doc/conf/conf.xml: Added a configuration for the RiverService.

2011-03-07  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Added a section user-factory and collection-factory in
	  the factories part of the configuration.

2011-03-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Replaced the 'special' attribute from DESCRIBE with a 'uiprovider'
	  attribute.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  RiverSelect state is called to create the UI part of the describe
	  document.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Implemented the dynamic UI part of describe(). The static part is not
	  inserted into the describe document at the moment. We need a reference to
	  the previous states for this.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java,
	  src/main/java/de/intevation/flys/artifacts/model/River.java: New. A model
	  class that represents a river and its factory to create concrete river
	  instances.
	  NOTE: Currently, this is just a mockup. The factory just returns two
	  static rivers "Mosel" and "Saar" without a connection to a backend.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: The
	  input data of a state is initialized with empty StateData objects after
	  the State has been created.

	* doc/conf/artifacts/winfo.xml: Renamed the input data nodes of the states
	  which now fits better to the class name of the implementation.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  describe document returned by this artifact now contains the current state
	  and the reachable states.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The transitions are put into the TransitionEngine with the ID of the state
	  - not longer with the artifact name. On this way, we are able to fetch
	  just the transitions for a specific state, instead of all the transitions
	  of an artifact.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Describe()
	  returns the artifact's uuid and hash value. The whole implementation of
	  describe() is still outstanding.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Removed useless config stuff.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Removed
	  useless methods, and improved the init process - the first state is set as
	  the current state for this artifact.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/GaugeSelect.java: New.
	  The states are used in the first two steps of the WINFOArtifact.
	  Currently, they just implement stubs of the necessary methods setup() and
	  describe().

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/Transition.java:
	  Removed. These classes are placed in the artifact-database now.

	* src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  Adapted imports of Transition.

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: New.
	  This factory should be used to create concrete State objects.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: Added
	  a constant key to store the StateEngine in the context.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  New method that initializes the states at application start.

2011-02-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java: New. The
	  interface description of a state.

	* src/main/java/de/intevation/flys/artifacts/transitions/Transition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java:
	  New. The interface description and a default implementation of a
	  transition.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java:
	  New. The TransitionEngine stores all transitions for each artifact and
	  should be used to determine, if an artifact can advance from one state to
	  another.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  New. Transitions should be created by using this class.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: New.
	  The Flys context. It currently defines keys to store important components
	  in the context.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  New. The context factory initializes the basic components of the
	  application. Currently, the TransitionEngine is created and all artifacts
	  with its transitions are read from the global configuration and stored in
	  the FLYSContext.

	* pom.xml: Added a dependency to the 'artifacts-common' package.

	* doc/conf/artifacts/winfo.xml: Corrected the classname of the
	  DefaultTransition.

	* doc/conf/conf.xml: Added FLYSContextFactory as context-factory.

2011-02-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: An initial configuration file for the FLYS artifact
	  server.

	* doc/conf/artifacts/winfo.xml: An initial transition configuration of an
	  WINFO artifact.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: A stub of
	  an artifact for a WINFO parameterization.

	* pom.xml: Set the source code version to 1.5.

2011-02-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/**, pom.xml: Added initial maven project.
	* ChangeLog: new.
