Class AbstractGrailsArtefactTransformer

java.lang.Object

org.codehaus.groovy.grails.compiler.injection.AbstractGrailsArtefactTransformer

All Implemented Interfaces:

java.lang.Comparable, ClassInjector, GrailsArtefactClassInjector

public abstract class AbstractGrailsArtefactTransformer
extends java.lang.Object
implements GrailsArtefactClassInjector, java.lang.Comparable

Abstract transformer that takes an implementation class and creates methods in a target ClassNode that delegate to that implementation class. Subclasses should override to provide the implementation class details

Since:

2.0
