ConnectorTutorial

public static class ConnectorTutorial.SitedRectangle
extends BasicRectangle

SitedRectangle is a class that provides four sites that we use in the examples to attach connectors to. In this example, we make life easy by using an instance of the BoundsGeometry class, but in general, figures will want to define their own sites. One thing to note about this figure: it does not itself contain the code that re-routes the attached connectors. Although it could override transform() and translate, in general it is better for this kind of routing to be initiated by the interaction code.
