Method Detail

process

public void process(GeneratedMetamodel metamodel)

Description copied from interface: IXtext2EcorePostProcessor

Process the given metatmodel (e.g. set default values, make references bi-directional, ...)

Specified by:

process in interface IXtext2EcorePostProcessor

Parameters:

metamodel - the metatmodel to augment

getResourceLoader

protected org.eclipse.emf.mwe.core.resources.ResourceLoader getResourceLoader(GeneratedMetamodel metamodel)

Parameters:

metamodel - the metamodel to augment

Parameters:

metamodel - the metamodel to augment

Returns:

the executionContext used to perform the xtend processing

loadXtendFile

protected org.eclipse.xtend.expression.Resource loadXtendFile(GeneratedMetamodel metamodel)

Expects an Xtend file named MyDslPostProcessor.ext with an extension with signature process(xtext::GeneratedMetamodel) in the same folder as the grammar file.

Parameters:

metamodel - the metamodel to augment

Returns:

the xtendFile to execute

fireXtendFileLoaded

protected void fireXtendFileLoaded()

notify subclasses that the xtend file was successfully loaded

clearCachedXtendFile

protected final void clearCachedXtendFile()

Sets cached Xtend file to null so it can be reloaded in loadXtendFile(GeneratedMetamodel)
