Method Detail

addEdge

void addEdge(N from,
             N to)

Adds an edge to the graph between 2 nodes. If the edge is already present no change is made.

Parameters:

from - out node for the edge.

to - in node for the edge.

removeEdge

void removeEdge(N from,
                N to)

Removes an edge between 2 nodes in the graph. If the edge is not present no change is made.

Parameters:

from - out node for the edge to remove.

to - in node for the edge to remove.

containsEdge

boolean containsEdge(N from,
                     N to)

Returns:

true if the graph contains an edge the 2 nodes false otherwise.

getNodes

List<N> getNodes()

Returns:

a list of the nodes that compose the graph. No ordering is implied.

addNode

void addNode(N node)

Adds a node to the graph. Initially the added node has no successors or predecessors. ; as a consequence it is considered both a head and tail for the graph.

Parameters:

node - a node to add to the graph.

See Also:

DirectedGraph.getHeads(), DirectedGraph.getTails()

removeNode

void removeNode(N node)

Removes a node from the graph. If the node is not found in the graph, no change is made.

Parameters:

node - the node to be removed.

containsNode

boolean containsNode(N node)

Parameters:

node - node that we want to know if the graph constains.

Returns:

true if the graph contains the node. false otherwise.
