  org.apache.tapestry.internal.transform.ComponentLifecycleMethodWorker

All Implemented Interfaces:

ComponentClassTransformWorker

public class ComponentLifecycleMethodWorker
extends Object
implements ComponentClassTransformWorker

Converts one of the methods of Component into a chain of command that, itself, invokes certain methods (render phase methods) marked with an annotation, or named in a specific way.

Constructor Summary

ComponentLifecycleMethodWorker(TransformMethodSignature lifecycleMethodSignature, Class<? extends Annotation> methodAnnotation, boolean reverse)
Normal method invocation: parent class, then methods in ascending alphabetical order.

Description copied from interface: ComponentClassTransformWorker

Invoked to perform a transformation on an as-yet unloaded component class, represented by the ClassTransformation instance. In some cases, the worker may make changes to the component model -- for example, a worker that deals with parameters may update the model to reflect those parameters.
