public DiGraph()

Method Detail

createNode

public abstract DiGraph.DiGraphNode<N,E> createNode(N nodeValue)

Description copied from class: Graph

Gets a node from the graph given a value. New nodes are created if that value has not been assigned a graph node. Values equality are compared using Object.equals.

Specified by:

createNode in class Graph<N,E>

Parameters:

nodeValue - The node's value.

Returns:

The corresponding node in the graph.

getNodes

public abstract java.util.Collection<? extends DiGraph.DiGraphNode<N,E>> getNodes()

Description copied from class: Graph

Gets an immutable list of all nodes.

Specified by:

getNodes in interface AdjacencyGraph<N,E>

Specified by:

getNodes in class Graph<N,E>

getNode

public abstract DiGraph.DiGraphNode<N,E> getNode(N nodeValue)

Description copied from interface: AdjacencyGraph

Gets a node from the graph given a value. Values equality are compared using Object.equals.

Parameters:

nodeValue - The node's value.

Returns:

The corresponding node in the graph, null if there value has no corresponding node.
