public class GraphicalLocator
extends Locator

This class is an extension of the Locator actor that adds an outputRange parameter and an icon that is a circle with a radius defined by the value of this parameter. In addition, this class provides the output channel with a transmit property named "range" with value equal to the value of its outputRange parameter. Thus, if the output channel is an instance of LimitedRangeChannel, then the outputRange parameter will define the range of transmission.

Field Detail

outputRange

public Parameter outputRange

The output signal range. This is a double that defaults to 100.0. The icon for this sensor node includes a circle with this as its radius.

_circle

private EllipseAttribute _circle

Icon indicating the communication region.

Constructor Detail

GraphicalLocator

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

Construct an actor with the specified container and name.

Parameters:

container - The container.

name - The name.

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

clone

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

Clone the object into the specified workspace. The new object is not added to the directory of that workspace (you must do this yourself if you want it there). The result is an object with no container.

Overrides:

clone in class AtomicActor

Parameters:

workspace - The workspace for the cloned object.

Returns:

The new Attribute.

Throws:

java.lang.CloneNotSupportedException - Not thrown in this base class

See Also:

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

fire

public void fire()
          throws IllegalActionException

Generate an event on the output port that indicates the current position and time of the last input on the input port. Also, change the color of the icon to red and schedule another firing after 1.0 time unit to change it back to blue.

Specified by:

fire in interface Executable

Overrides:

fire in class Locator

Throws:

IllegalActionException - Not thrown in this base class.

initialize

public void initialize()
                throws IllegalActionException

Initialize the sensor node by setting its icon color to blue.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor

Throws:

IllegalActionException - If thrown by the base class.
