11 11  The KIELER Compiler (KiCo) project allows to register step-by-step model transformations on EObjects that could be written in Xtend or Java. 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.

83 +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:
84 +
85 +* 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!
86 +* 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.
87 +* name: An optional String name for this transformation. If nothing is entered here the ID will be used as a name.
88 +* 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 ==

21 -text
128 +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:

140 +* transformationIDs: List of Strings representing the transformation IDs and a pre-ordering. Note that KiCo may automatically modify the order to meet the dependencies of the referenced transformation IDs or transformation group IDs.

142 +* Returns: The EObject returned from the last model transformation called by KiCo.

157 +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.
