Method Summary

java.lang.Object	addEdge(java.lang.Object fromNode, java.lang.Object toNode, java.lang.Object edge) Return null if no existing edge is displaced by edge.
boolean	addNode(java.lang.Object node) Return true if the node is added successfully, false if the digraph does not change.
boolean	addNodes(java.util.Set nodes) Return true if adding the nodes changes the digraph.
void	clear() Remove all nodes and edges from the CEDigraph
void	clearEdges() Remove all the edges from the CEDigraph.
Bag	removeCEDigraph(CEDigraph digraph) Return a Bag of edges orphaned when digraph is removed
java.lang.Object	removeEdge(java.lang.Object fromNode, java.lang.Object toNode) Return the edge that connected fromNode to toNode, or null if no edge existed.
Bag	removeNode(java.lang.Object node) Return the Bag of orphaned edges that are removed with node
Bag	removeNodes(java.util.Set nodes) Return the Bag of edges orphaned edges when these nodes are removed.
Bag	retainNodes(java.util.Set nodes) Return a Bag of orphaned edges when the nodes are removed.
