Class Entity.ContainedObjectsIterator

java.lang.Object

ptolemy.kernel.util.NamedObj.ContainedObjectsIterator

ptolemy.kernel.Entity.ContainedObjectsIterator

All Implemented Interfaces:

java.util.Iterator

Direct Known Subclasses:

CompositeEntity.ContainedObjectsIterator, LazyTypedCompositeActor.ContainedObjectsIterator

Enclosing class:

Entity<T extends Port>

protected class Entity.ContainedObjectsIterator
extends NamedObj.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. In derived classes, they include relations, and entities as well. The user of this class should have read access on the workspace and hold it for the duration of the use of the iterator. Moreover, it should not modify the port or attribute list while using the iterator or it will get a ConcurrentModificationException.
