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.

_effigy

private PtolemyEffigy _effigy
The effigy representing the model.


_entity

private NamedObj _entity
The top-level entity read from the file or URL.


_graph

private JGraph _graph
The graph display pane.


_tableau

private Tableau _tableau
The tableau, if the model is displayed in its own window.

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.

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException
Clone the actor into the specified workspace.

Overrides:
clone in class AtomicActor
Parameters:
workspace - The workspace for the new object.
Returns:
A new actor.
Throws:
java.lang.CloneNotSupportedException - If a derived class has an attribute that cannot be cloned.

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
