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.

public boolean hasNext()
```
    Return true if the iteration has more elements. In this base class, this returns true if there are more attributes or ports.
    
    Specified by:
    
    hasNext in interface java.util.Iterator
    
    Overrides:
    
    hasNext in class NamedObj.ContainedObjectsIterator
    
    Returns:
    
    True if there are more attributes or ports.
  - next
```
public java.lang.Object next()
```
    Return the next element in the iteration. In this base class, this is the next attribute or port.
    
    Specified by:
    
    next in interface java.util.Iterator
    
    Overrides:
    
    next in class NamedObj.ContainedObjectsIterator
    
    Returns:
    
    The next attribute or port.
  - remove
