Method Summary

Edge	newEdge(Node source, Node target) Create a new edge.
Edge	newEdge(Node source, Node target, float weight, boolean directed) Creates a new edge.
Edge	newEdge(java.lang.String id, Node source, Node target, float weight, boolean directed) Creates a new edge.
Node	newNode() Create a new node, with default identifier.
Node	newNode(java.lang.String id) Create a new node with an identifier.

Method Detail

newNode

Node newNode()

Create a new node, with default identifier.

Returns:

a new node instance

newNode

Node newNode(java.lang.String id)

Create a new node with an identifier. If id is null a default identifier is used.

Parameters:

id - a unique identifier, could be null

Returns:

a new node instance

newEdge

Edge newEdge(Node source,
             Node target)

Create a new edge. This method don't force the type of edge (directed or undirected). That means it is directed by default but will be considered as undirected if queried from an UndirectedGraph.

Edge's weight is 1.0 by default.

Parameters:

source - the edge's source

target - the edge's target

Returns:

a new proper edge instance

newEdge

Edge newEdge(Node source,
             Node target,
             float weight,
             boolean directed)

Creates a new edge.

Parameters:

source - the edge's source

target - the edge's targer

weight - the edge's weight

directed - the edge's type

Returns:

a new mixed edge instance

newEdge

Edge newEdge(java.lang.String id,
             Node source,
             Node target,
             float weight,
             boolean directed)

Creates a new edge.

Parameters:

id - a unique identifier, could be null

source - the edge's source

target - the edge's targer

weight - the edge's weight

directed - the edge's type

Returns:

a new mixed edge instance
