All Implemented Interfaces:

org.jgraph.graph.CellView, Serializable

public class JGraphpadEdgeView

extends org.jgraph.graph.EdgeView

Edge view that supports moveable ports. Note: The offset for the port depends on the edge, and is therefore stored in the edge's attributes. It is not required to provide a custom port view, as the port offset is returned from within the overridden getNearestPoint(boolean).
