Class CompositeBag<E>

  org.eclipse.ocl.examples.eventmanager.CompositeIterable<E>
      org.eclipse.ocl.examples.eventmanager.util.CompositeCollection<E>
          org.eclipse.ocl.examples.eventmanager.util.CompositeBag<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, Bag<E>

public class CompositeBag<E>
extends CompositeCollection<E>
implements Bag<E>

A Bag implementation that allows for multiple occurrences of elements in the nested collections and allows for them to be counted. In particular, if the nested collections in turn conform to the Bag interface, their count(Object) operation will be used to determine the composite object count.
