Teichmann <sascha.teichmann@intevation.de> + + Use improved caching for cross section data. + !!! This commit needs heavy testing !!! + + * src/main/java/de/intevation/flys/artifacts/services/CrossSectionKMService.java: + Refactored to provide the map to determine the nearest cross section line + neighbors for a given km to the public. This is a bit hackish because + it hhould have its own factory which is then used by this service and + other parts of the code. + + * src/main/java/de/intevation/flys/artifacts/CrossSectionArtifact.java: + searchCrossSectionLine() now returns a FastCrossSectionLine. To find this + line efficiently it uses the map of the CrossSectionKMService which + already provides a nearest neighbor searching mechanism for cross + section lines. The FastCrossSectionLine is fetched with the + FastCrossSectionLineFactory which uses a cache as described in the + previous commit. + + * src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java + src/main/java/de/intevation/flys/artifacts/WaterLineArtifact.java, + src/main/java/de/intevation/flys/artifacts/model/CrossSectionWaterLineFacet.java, + src/main/java/de/intevation/flys/artifacts/StaticWKmsArtifact.java, + src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Uses + the FastCrossSectionLine instead of CrossSectionLines now. + + * src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionLine.java: + Added method fetchCrossSectionProfile() to access the point data in + the profile generating compatible way. + + * src/main/java/de/intevation/flys/artifacts/ChartArtifact.java: Removed + superfluous import. + 2012-01-16 Sascha L.
