Examples of ptolemy.kernel.Entity$ContainedObjectsIterator

ptolemy.kernel.Entity
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.

            // Mirror the change in mirror ports.
            MultiCompositeActor container = (MultiCompositeActor) getContainer();
            Iterator entities = container.entityList().iterator();


            while (entities.hasNext()) {
                Entity entity = (Entity) entities.next();
                Port mirrorPort = entity.getPort(getName());


                if (mirrorPort instanceof RefinementPort) {
                    RefinementPort castPort = (RefinementPort) mirrorPort;
                    boolean disableStatus = castPort._mirrorDisable;
