Interface GraphModelListener

All Superinterfaces:

AttributeValueListener, EventListener

All Known Subinterfaces:

EquipmentModelListener, NetworkModelListener

All Known Implementing Classes:

IlpAbstractEquipmentModelListener, IlpAbstractNetworkModelListener

public interface GraphModelListener
extends EventListener, AttributeValueListener

This interface allows the observing of changes to an IlpGraphModel. Since an IlpGraphModel potentially contains an infinite number of objects, and to permit load-on-demand, a model listener maintains a list of objects which it is interested in, called the "observation scope".

Since:

JTGO 4.0

Method Summary

void	attributeValueChange(AttributeValueEvent event) Invoked when the attribute of an object contained in the model changes.
void	eventSeriesBegin() Invoked before a series of events begins.
void	eventSeriesEnd() Invoked after a series of events has ended.
boolean	isObserved(IlpRepresentationObject object) Returns true if the object is a member of this listener's observation scope, in other words, if this listener is interested in being notified about the object.

Method Detail

isObserved

boolean isObserved(IlpRepresentationObject object)

Returns true if the object is a member of this listener's observation scope, in other words, if this listener is interested in being notified about the object.

The IlpGraphModel is not allowed to send an event to this listener if the event is about an object that is not in the observation scope.

eventSeriesBegin

void eventSeriesBegin()

Invoked before a series of events begins.

eventSeriesEnd

void eventSeriesEnd()

Invoked after a series of events has ended.

attributeValueChange

void attributeValueChange(AttributeValueEvent event)

Invoked when the attribute of an object contained in the model changes.

Specified by:

attributeValueChange in interface AttributeValueListener

Parameters:

event - An event of type AttributeValueEvent.
