The default implementation creates a GenericNodeRealizer copy of the specified prototype realizer and adopts the port's bounds as well as the port's selection state.

Called from contains(NodePort, double, double), findIntersection(NodePort, double, double, double, double, java.awt.geom.Point2D), and paint(NodePort, java.awt.Graphics2D).

Parameters:

prototype - a GenericNodeRealizer instance

port - the NodePort instance that is represented by the created NodeRealizer instance.

Returns:

a GenericNodeRealizer that represents the specified NodePort instance.
