_update

protected boolean _update()

Description copied from class: ActorGraphModel

Update the graph model. This is called whenever a change request is executed. In this class the internal set of link objects is created to represent each of the links in the graph, and to remove any link objects that are incorrect (e.g., do not have both ends in the model). This method is usually called just before issuing a graph event. If this method returns false, then the graph event should not be issued, because further changes are necessary.

Overrides:

_update in class ActorGraphModel

Returns:

True if the model was successfully updated, or false if further change requests were queued.
