Constructor Detail

MirrorComposite

public MirrorComposite(CompositeEntity container,
                       java.lang.String name)
                throws IllegalActionException,
                       NameDuplicationException

Create an actor with a name and a container. The container argument must not be null, or a NullPointerException will be thrown. This actor 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:

container - The container actor.

name - The name of this actor.

Throws:

IllegalActionException - If the container is incompatible with this actor.

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

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the object into the specified workspace. This overrides the base class to set up the associations in the mirror ports and to set a flag indicating that cloning is complete.

Overrides:

clone in class CompositeActor

Parameters:

workspace - The workspace for the new object.

Returns:

A new NamedObj.

Throws:

java.lang.CloneNotSupportedException - If any of the attributes cannot be cloned.

See Also:

InstantiableNamedObj.exportMoML(Writer, int, String)

newPort

public Port newPort(java.lang.String name)
             throws NameDuplicationException

Override the base class to return a specialized port.

Overrides:

newPort in class TypedCompositeActor

Parameters:

name - The name of the port to create.

Returns:

A new instance of IteratePort, an inner class.

Throws:

NameDuplicationException - If the container already has a port with this name.

_addEntity

protected void _addEntity(ComponentEntity entity)
                   throws IllegalActionException,
                          NameDuplicationException

Override the base class to queue a change request to remove any previously contained entity and its mirrored ports, and to mirror the ports of the added entity.

Overrides:

_addEntity in class TypedCompositeActor

Parameters:

entity - Entity to contain.

Throws:

IllegalActionException - If the entity has no name, or the action would result in a recursive containment structure, or the argument does not implement the TypedActor interface.

NameDuplicationException - If the name collides with a name already on the actor contents list, or if the added element is a class definition.

_addPort

protected void _addPort(Port port)
                 throws IllegalActionException,
                        NameDuplicationException

Add a port to this actor. This overrides the base class to mirror the new port in the contained actor, if there is one, and to establish a connection to a port on the contained actor.

Overrides:

_addPort in class TypedCompositeActor

Parameters:

port - The TypedIOPort to add to this actor.

Throws:

IllegalActionException - If the port is not an instance of IteratePort, or the port has no name.

NameDuplicationException - If the port name collides with a name already in the actor.

_exportMoMLContents

protected void _exportMoMLContents(java.io.Writer output,
                                   int depth)
                            throws java.io.IOException

Override the base class to describe contained entities, attributes, and ports, but not inside links or relations. The rest of the contents are generated automatically when a contained entity is inserted.

Overrides:

_exportMoMLContents in class CompositeEntity

Parameters:

output - The output to write to.

depth - The depth in the hierarchy, to determine indenting.

Throws:

java.io.IOException - If an I/O error occurs.

See Also:

NamedObj.exportMoML(Writer, int)

_removeEntity

protected void _removeEntity(ComponentEntity entity)

Override the base class to remove the ports and inside relations of this actor. This method assumes the caller has write access on the workspace.

Overrides:

_removeEntity in class CompositeEntity

Parameters:

entity - The entity being removed from this entity.

_removePort

protected void _removePort(Port port)

Override the base class to remove the associated port on the inside entity and the link to it, if there is one. This method assumes the caller has write access on the workspace.

Overrides:

_removePort in class Entity

Parameters:

port - The port being removed from this entity.
