Examples of ComponentEntity

ptolemy.kernel.ComponentEntity

A ComponentEntity is a component in a CompositeEntity. It might itself be composite, but in this base class it is assumed to be atomic (meaning that it cannot contain components).

Derived classes may further constrain the container to be a subclass of CompositeEntity. To do this, they should override the protected method _checkContainer() to throw an exception.

A ComponentEntity can contain instances of ComponentPort. Derived classes may further constrain to a subclass of ComponentPort. To do this, they should override the public method newPort() to create a port of the appropriate subclass, and the protected method _addPort() to throw an exception if its argument is a port that is not of the appropriate subclass. @author John S.
