public abstract class MutableGraphSupport

extends Object

implements MutableGraphModel, Serializable

An abstract class that makes it easier to implement your own version of MutableGraphModel. This class basically includes the code for event notifications, so that you don't have to write that. It also provides a few utility methods.

canConnect

public boolean canConnect(Object fromPort,
                          Object toPort,
                          Class edgeClass)

Return true if the two given ports can be connected by the given kind of edge. By default ignore edgeClass and call canConnect(port,port).

Specified by:

canConnect in interface MutableGraphModel

connect

public Object connect(Object fromPort,
                      Object toPort,
                      Class edgeClass)

Contruct and add a new edge of the given kind. By default ignore edgeClass and call connect(port,port).
