# HG changeset patch # User Tim Englich # Date 1260279501 0 # Node ID a887074460b60cf202ba382eabde14ec30734cd0 # Parent 1b9ca0f2d4989c76e37103045ca5a375ae94e33d Last Step of the Refactoring Work on the Transition Model. Splitted Businesslogic between States and Transitions. Splitted the ConfigurationElements of State and Transition in several XML-Fragments. gnv-artifacts/trunk@403 c6561f87-3c4e-4783-a992-168aeb5c3f6f diff -r 1b9ca0f2d498 -r a887074460b6 gnv-artifacts/ChangeLog --- a/gnv-artifacts/ChangeLog Tue Dec 08 11:18:27 2009 +0000 +++ b/gnv-artifacts/ChangeLog Tue Dec 08 13:38:21 2009 +0000 @@ -1,3 +1,26 @@ +2009-12-08 Tim Englich + + * src/main/java/de/intevation/gnv/transition/profile: + Removed empty needless package. + * src/main/java/de/intevation/gnv/transition/TransitionFactory.java: + src/main/java/de/intevation/gnv/transition/ValueCompareTransition.java, + src/main/java/de/intevation/gnv/transition/TransitionBase.java, + src/main/java/de/intevation/gnv/transition/Transition.java, + src/main/java/de/intevation/gnv/transition/DefaultTransition.java: + The new Transitions which has the only job to provide the connectios between + the different States and look if it is Possible to go the different Ways. + * src/main/java/de/intevation/gnv/state/StateBase.java, + src/main/java/de/intevation/gnv/state/State.java: + Removed the Logic to descide which State is be reacable as next. + Now the Transition configured in the Artifacts will do that according + to the modified TransitionModel. + * src/main/java/de/intevation/gnv/artifacts/GNVArtifactBase.java (transitions): + Added the Transitions to the Artifact and changed the Logic. + Now the Transition is able to decide if it could be uses or not. + * doc/conf/products/verticalprofile/*.xml: + Modified the Configuration.
