Constructor Detail

TDLTransition

public TDLTransition(Workspace workspace)
              throws IllegalActionException,
                     NameDuplicationException

Construct a transition contained by the specified entity.

Parameters:

workspace - The workspace for synchronization and version tracking.

Throws:

IllegalActionException - If the container is incompatible with this transition.

NameDuplicationException - If the name coincides with any relation already in the container.

TDLTransition

public TDLTransition(TDLActor container,
                     java.lang.String name)
              throws IllegalActionException,
                     NameDuplicationException

Construct a transition with the given name contained by the specified entity. The container argument must not be null, or a NullPointerException will be thrown. This transition will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string.

Parameters:

container - The container.

name - The name of the transition.

Throws:

IllegalActionException - If the container is incompatible with this transition.

NameDuplicationException - If the name coincides with any relation already in the container.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

Description copied from class: Transition

React to a change in an attribute. If the changed attribute is the preemptive parameter, evaluate the parameter. If the parameter is given an expression that does not evaluate to a boolean value, throw an exception; otherwise increment the version number of the workspace.

Overrides:

attributeChanged in class Transition

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If thrown by the superclass attributeChanged() method, or the changed attribute is the preemptive parameter and is given an expression that does not evaluate to a boolean value.
