Method Detail

loadXtendFile

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

Description copied from class: XtendXtext2EcorePostProcessor

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

Overrides:

loadXtendFile in class XtendXtext2EcorePostProcessor

Parameters:

metamodel - the metamodel to augment

Returns:

the xtendFile to execute

getResourceLoader

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

Overrides:

getResourceLoader in class XtendXtext2EcorePostProcessor

Parameters:

metamodel - the metamodel to augment

Returns:

the resource loader used to load resources during the xtend processing

createClassLoader

protected java.lang.ClassLoader createClassLoader(org.eclipse.jdt.core.IJavaProject javaProject)
                                           throws org.eclipse.core.runtime.CoreException

Throws:

org.eclipse.core.runtime.CoreException

resourceChanged

public void resourceChanged(org.eclipse.core.resources.IResourceChangeEvent event)

Description copied from interface: org.eclipse.core.resources.IResourceChangeListener

Notifies this listener that some resource changes are happening, or have already happened.

The supplied event gives details. This event object (and the resource delta within it) is valid only for the duration of the invocation of this method.

Note: This method is called by the platform; it is not intended to be called directly by clients.

Note that during resource change event notification, further changes to resources may be disallowed.

Specified by:

resourceChanged in interface org.eclipse.core.resources.IResourceChangeListener

Parameters:

event - the resource change event
