Class PersistAnnotationWorker

java.lang.Object
  org.apache.tapestry.annotations.PersistAnnotationWorker

All Implemented Interfaces:

MethodAnnotationEnhancementWorker

public class PersistAnnotationWorker
extends Object
implements MethodAnnotationEnhancementWorker

Allow a property to be marked as persistent, and (optionally) allows a strategy to be set. Works by adding a new IPropertySpecification to the IComponentSpecification.

The Persist annotation may optionally by accompanied by a InitialValue annotation; this sets the initial value, as a binding reference, used to initialize and re-initialize the property.

4.0
