public class ModelDisplay
extends AbstractPlaceableActor
implements ChangeListener

This actor opens a window to display the specified model. If inputs are provided, they are expected to be MoML strings that are to be applied to the model. This can be used, for example, to create animations.

Field Detail

modelURL

public FileParameter modelURL

The file or URL from which to read the starting point model. The model is read when this parameter is set or changed.

input

public TypedIOPort input

The input port through which to provide MoML to modify the model. This has type string.

Constructor Detail

ModelDisplay

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

Construct an actor with the specified container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the entity cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a change in an attribute. If the attribute is modelURL, then read the specified URL and parse it to create the entity to display.

Overrides:

attributeChanged in class NamedObj

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (not thrown in this base class).

changeExecuted

public void changeExecuted(ChangeRequest change)

Do nothing.

Specified by:

changeExecuted in interface ChangeListener

Parameters:

change - The change that succeeded.

changeFailed

public void changeFailed(ChangeRequest change,
                         java.lang.Exception exception)

Stop executing the model.

Specified by:

changeFailed in interface ChangeListener

Parameters:

change - The change.

exception - The exception.

fire

public void fire()
          throws IllegalActionException

Read the input, if there is any, and issue a change request to apply the MoML in the input to the displayed model.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor

Throws:

IllegalActionException - If there is an error reading the input.

initialize

public void initialize()
                throws IllegalActionException

If the model is not yet displayed, then display it in its own window.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor

Throws:

IllegalActionException - If there is an constructing the display.

place

public void place(java.awt.Container container)

Place the display in the specified container.

Specified by:

place in interface Placeable

Specified by:

place in class AbstractPlaceableActor

Parameters:

container - The container, or null to remove it from any existing container.
