Examples of ComponentEventHandler

org.apache.tapestry.ComponentEventHandler
Handler for a {@link ComponentEvent}, notified when a non-null value is returned from some event handler method.
TODO: Multiple handlers for different result types / strategy pattern?
org.apache.tapestry5.services.ComponentEventHandler
Interface used with {@link org.apache.tapestry5.services.transform.TransformationSupport#addEventHandler(String,int,String,ComponentEventHandler)}} (and, in the old API, {@link ClassTransformation#addComponentEventHandler(String,int,String,ComponentEventHandler)}). @since 5.2.0
