21 21  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.

124 124  == Compilation ==
125 125  
126 -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:
