public class TypeAnimatorApplet
extends MoMLViewerApplet

An applet that demonstrates the Ptolemy II type system. This applet identifies attributes whose names match entity names, followed by an underscore, followed by a port name. If that attribute has an icon (i.e. it is a visible attribute), then the icon is set to a text string that gives the type of the port.

To use this applet, create an MoML file with the model that you want to animate, and insert visible attributes in it. Rename these so that the name has the form "entityname_portname", to illustrate the port of the specified entity.

Since:

Ptolemy II 1.0

Method Detail

managerStateChanged

public void managerStateChanged(Manager manager)

React to the fact that the manager state has changed. This is called by the manager. In this class, we detect the start of execution of the model to initialize the type displays with the initial types.

Specified by:

managerStateChanged in interface ExecutionListener

Overrides:

managerStateChanged in class PtolemyApplet

Parameters:

manager - The manager that changed.

See Also:

Manager.getState()

start

public void start()

Override the base class to avoid executing the model automatically when the applet starts, and instead to update type displays to the initial types of the ports.

Overrides:

start in class MoMLViewerApplet

_createModel

protected NamedObj _createModel(Workspace workspace)
                         throws java.lang.Exception

Create the model. This overrides the base class to attach type listeners to all the ports contained by top-level entities.

Overrides:

_createModel in class MoMLViewerApplet

Parameters:

workspace - The workspace in which to create the model.

Returns:

The model that was created

Throws:

java.lang.Exception - If there was a problem creating the model.

_updateAllTypeDisplays

private void _updateAllTypeDisplays()

_updateTypeDisplay

private void _updateTypeDisplay(TypedIOPort port)
