public class ModalPort
extends TypedIOPort

A port for modal models. This port mirrors certain changes to it in the ports of the controller and refinements of the modal model. It is designed to work closely with RefinementPort, since changes to the ports can be initiated in either class.

Constructor Detail

ModalPort

public ModalPort(Workspace workspace)
          throws IllegalActionException

Construct a port in the given workspace.

Parameters:

workspace - The workspace.

Throws:

IllegalActionException - If the port is not of an acceptable class for the container, or if the container does not implement the TypedActor interface.

ModalPort

public ModalPort(ComponentEntity container,
                 java.lang.String name)
          throws IllegalActionException,
                 NameDuplicationException

Construct a port with a containing actor and a name that is neither an input nor an output. The specified container must implement the TypedActor interface, or an exception will be thrown.

Parameters:

container - The container actor.

name - The name of the port.

Throws:

IllegalActionException - If the port is not of an acceptable class for the container, or if the container does not implement the TypedActor interface.

NameDuplicationException - If the name coincides with a port already in the container.

Method Detail

moveDown

public int moveDown()
             throws IllegalActionException

Move this object down by one in the list of attributes of its container. If this object is already last, do nothing. This method overrides the base class to mirror the change in any mirror ports. Increment the version of the workspace.

Specified by:

moveDown in interface Moveable

Overrides:

moveDown in class Port

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container.

moveToFirst

public int moveToFirst()
                throws IllegalActionException

Move this object to the first position in the list of attributes of the container. If this object is already first, do nothing. Increment the version of the workspace. This method overrides the base class to mirror the change in any mirror ports.

Specified by:

moveToFirst in interface Moveable

Overrides:

moveToFirst in class Port

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container.

moveToIndex

public int moveToIndex(int index)
                throws IllegalActionException

Move this object to the specified position in the list of attributes of the container. If this object is already at the specified position, do nothing. This method overrides the base class to mirror the change in any mirror ports. Increment the version of the workspace.

Specified by:

moveToIndex in interface Moveable

Overrides:

moveToIndex in class Port

Parameters:

index - The position to move this object to.

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container or if the index is out of bounds.

moveToLast

public int moveToLast()
               throws IllegalActionException

Move this object to the last position in the list of attributes of the container. If this object is already last, do nothing. This method overrides the base class to mirror the change in any mirror ports. Increment the version of the workspace.

Specified by:

moveToLast in interface Moveable

Overrides:

moveToLast in class Port

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container.

moveUp

public int moveUp()
           throws IllegalActionException

Move this object up by one in the list of attributes of the container. If this object is already first, do nothing. This method overrides the base class to mirror the change in any mirror ports. Increment the version of the workspace.

Specified by:

moveUp in interface Moveable

Overrides:

moveUp in class Port

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

setContainer

public void setContainer(Entity container)
                  throws IllegalActionException,
                         NameDuplicationException

Override the base class so that if the port is being removed from the current container, then it is also removed from the controller and from each of the refinements. This method is write-synchronized on the workspace.

Overrides:

setContainer in class IOPort

Parameters:

container - The proposed container.

Throws:

IllegalActionException - If the proposed container is not a ComponentEntity, doesn't implement Actor, or has no name, or the port and container are not in the same workspace. Or it's not null

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

Port.getContainer(), Port._checkContainer(Entity)

setInput

public void setInput(boolean isInput)
              throws IllegalActionException

If the argument is true, make the port an input port. If the argument is false, make the port not an input port. This method overrides the base class to make the same change on the mirror ports in the controller and state refinments. This method invalidates the schedule and resolved types of the director of the container, if there is one. It is write-synchronized on the workspace, and increments the version of the workspace.

Overrides:

setInput in class IOPort

Parameters:

isInput - True to make the port an input.

Throws:

IllegalActionException - If changing the port status is not permitted.

setMultiport

public void setMultiport(boolean isMultiport)

If the argument is true, make the port a multiport. If the argument is false, make the port not a multiport. This method overrides the base class to make the same change on the mirror ports in the controller and state refinments. This method invalidates the schedule and resolved types of the director of the container, if there is one. It is write-synchronized on the workspace, and increments the version of the workspace.

Overrides:

setMultiport in class IOPort

Parameters:
