Method Detail

isDirected

public boolean isDirected()

Deprecated. As of version 1.4, replaced by edu.uci.ics.jung.graph.utils.PredicateUtils#enforcesDirected(Graph) and edu.uci.ics.jung.graph.utils.PredicateUtils#enforcesUndirected(Graph).

Returns true if each edge of this graph is directed, and false if each edge of this graph is undirected. If some edges are directed and some are not, throws FatalException.

addVertex

public Vertex addVertex(Vertex v)

Adds v to this graph, and returns a reference to the added vertex.

Parameters:

v - the vertex to be added

addEdge

public Edge addEdge(Edge e)

Adds e to this graph, and returns a reference to the added vertex.

Parameters:

e - the edge to be added

removeVertex

public void removeVertex(Vertex v)

Removes v from this graph. Any edges incident to v which become ill-formed (as defined in the documentation for ArchetypeEdge) as a result of removing v are also removed from this graph. Throws IllegalArgumentException if v is not in this graph.

removeEdge

public void removeEdge(Edge e)

Removes e from this graph. Throws IllegalArgumentException if e is not in this graph.
