Package org.codehaus.groovy.control.customizers.builder

Class InlinedASTCustomizerFactory

java.lang.Object

groovy.util.AbstractFactory

org.codehaus.groovy.control.customizers.builder.InlinedASTCustomizerFactory

All Implemented Interfaces:

Factory, PostCompletionFactory

public class InlinedASTCustomizerFactory
extends AbstractFactory
implements PostCompletionFactory

This factory lets a user define a compilation customizer without having to define an anonymous inner class.

Here is an example, which only logs the class name during compilation:

 inline(phase:'CONVERSION') { source, context, classNode ->
     println "visiting $classNode"
 }
 

Since:

2.1.0

builder - the active builder

node - the current node

childContent - the nested closure content

Returns:

false to continue normal processing

postCompleteNode
