Class ControllerActionTransformer

java.lang.Object

org.codehaus.groovy.grails.compiler.web.ControllerActionTransformer

All Implemented Interfaces:

org.codehaus.groovy.grails.compiler.injection.AnnotatedClassInjector, org.codehaus.groovy.grails.compiler.injection.ClassInjector, org.codehaus.groovy.grails.compiler.injection.GrailsArtefactClassInjector

public class ControllerActionTransformer
extends java.lang.Object
implements org.codehaus.groovy.grails.compiler.injection.GrailsArtefactClassInjector, org.codehaus.groovy.grails.compiler.injection.AnnotatedClassInjector

Enhances controller classes by converting closures actions to method actions and binding request parameters to action arguments.
