Constructor Detail

TransformationAttribute.TransformationListener

public TransformationAttribute.TransformationListener(Manager manager,
                                                      java.lang.String name,
                                                      CompositeEntity model)
                                               throws IllegalActionException,
                                                      NameDuplicationException

Construct an attribute with the given name contained by the specified entity. The container argument must not be null, or a NullPointerException will be thrown. This attribute 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. Increment the version of the workspace.

Parameters:

manager - The container of this listener.

name - The name of this attribute.

model - The model to be transformed.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

Method Detail

executionError

public void executionError(Manager manager,
                           java.lang.Throwable throwable)

Do nothing.

Specified by:

executionError in interface ExecutionListener

Parameters:

manager - The manager controlling the execution.

throwable - The throwable to report.

executionFinished

public void executionFinished(Manager manager)

Do nothing.

Specified by:

executionFinished in interface ExecutionListener

Parameters:

manager - The manager controlling the execution.

managerStateChanged

public void managerStateChanged(Manager manager)

If the manager's state becomes Manager.INITIALIZING, set the model parameter in the model updater of the transformation attribute to contain the container of the transformation attribute. Do nothing otherwise.

Specified by:

managerStateChanged in interface ExecutionListener

Parameters:

manager - The manager controlling the execution.
