Examples of ptolemy.kernel.util.InvalidStateException

ptolemy.kernel.util.InvalidStateException
Some object or set of objects has a state that is not permitted. E.g., a NamedObj has a null name. Or a topology has inconsistent or contradictory information in it, e.g. an entity contains a port that has a different entity as it container. Our design should make it impossible for this exception to ever occur, so occurrence is a bug. @author Edward A.
