Class MetaAnnotationWorker

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

All Implemented Interfaces:

ClassAnnotationEnhancementWorker

public class MetaAnnotationWorker
extends Object
implements ClassAnnotationEnhancementWorker

Recognizes the Meta annotation, and converts it into properties on the specification. It is desirable to have meta data in base classes be "merged" with meta data from sub classes, with the sub classes overriding any conflicting elements from the base class. What we do is work our way up the inheritance tree to java.lang.Object and work with each Meta annotation we find.
