All Implemented Interfaces:

java.util.Iterator

Enclosing class:

CompositeEntity

protected class CompositeEntity.ContainedObjectsIterator
extends Entity.ContainedObjectsIterator

This class is an iterator over all the contained objects (all instances of NamedObj). In this class, the contained objects are attributes first, then ports, then entities, then relations.

Field Summary

Constructor Summary

CompositeEntity.ContainedObjectsIterator()
Create an iterator over all the contained objects, which for CompositeEntities are attributes, ports, classes entities, and relations.

Method Summary

boolean	hasNext() Return true if the iteration has more elements.
java.lang.Object	next() Return the next element in the iteration.
