These transformations are registered using an extension point provided (see below). After registering transformations these can be used by simply call the KielerCompiler compilation method as also explained further below.

76 +The defined class must extend "de.cau.cs.kieler.kico.Transformation" and must implement the methods defined in "de.cau.cs.kieler.kico.ITransformation". These are
77 +
78 +* getId(): Returns a unique String ID for this transformation. This is the ID the transformation will be referenced throughout KiCo.
79 +* getName(): Optionally return a String name for this transformation. If null is returned here the ID will be used as a name.
80 +* getDependencies(): Optionally return a List<String> of other transformation IDs that must run BEFORE this transformation. If null is returned then this means there are no dependencies.
81 +* transform(EObject): Returns an EObject and does the central transformation.

86 +The defined class can be freely chosen and does not need to extend or implement any other class or interface. Although you have to give more information in the extension element now:
87 +
88 +* class: The class where the transform method is implemented in
89 +* method: The name of the transformation method. Its signature must ensure that it returns an EObject an only take an EObject argument. Otherwise it cannot be found by KiCo.
90 +* id: The unique String ID for this transformation. This is the ID the transformation will be referenced throughout KiCo.
91 +* name: An optional String name for this transformation. If nothing is entered here the ID will be used as a name.
92 +* dependencies: An optional String as comma separated list of other transformation IDs that must run AFTER this transformation down the compile-chain. This means if the current transformation is selected to run, all transformations that have dependencies on this will be run BEFORE. If nothing is entered here then this means there are no dependencies.
93 +)))
94 +|(((
95 +transformationGroup
96 +)))|(((
97 +Sometimes you may want to group other transformations and give this group a specific transformation ID as a kind of shortcut. You can do this by using the transformationGroup element giving the following information:
98 +
99 +* id: The unique String ID for this transformation group. This is the ID the transformation group will be referenced throughout KiCo. It may also again be referenced by other transformation groups!
100 +* transformations: Groups must specify their transformations. Use a String as comma separated list of other transformation IDs or transformation group IDs that should represent this group. Note that the order will be implied by the referenced transformations itself although if there is a free degree of order it can be influenced by the order specified here in the group.
101 +* name: An optional String name for this transformation. If nothing is entered here the ID will be used as a name.
102 +* alternatives: When selected this group specifies alternatives only. When this group is referenced, the first transformation is selected if not any other transformation from this group is already in the list of selected transformations. This is an advanced feature.

19 19  == Compilation ==
20 20  
21 -text
142 +Once a bunch of model transformations are registered, these can simply be called using the KiCo central "KielerCompiler" class with its method compile(). This will be given a List<String> of transformation IDs or a comma separated String of transformation IDs as the first parameter. The second parameter is the EObject that is being transformed. It should meet the signature of the first model transformation called. Note that the actual model transformations that are done may vary because KiCo will automatically inspect the dependencies of each transformation requested (deep-recursively). If you do not like this to happen as an advanced user you can use a third parameter that will skip this autocompletion. Note that if you switch this off also NO transformation groups can be processed. Here is an overview and examples how to use the compile() method:

171 +This is an advanced compile method which can turn of auto-expansion with the last parameter. Use this with care! Note that if switching autoexpand off you cannot use transformation group IDs any more. Also no dependencies will be considered. The transformations will be applied straight forward in the order defined by the transformationIDs list.
