Method Detail

init

protected void init(Table table,
                    Graph graph,
                    int row)

Initialize a new Edge backed by an edge table. This method is used by the appropriate TupleManager instance, and should not be called directly by client code, unless by a client-supplied custom TupleManager.

Overrides:

init in class TableTuple

Parameters:

table - the edge Table

graph - the backing Graph

row - the row in the edge table to which this Node instance corresponds.

getGraph

public Graph getGraph()

Description copied from interface: Edge

Returns the graph of which this Edge is a member.

Specified by:

getGraph in interface Edge

Returns:

the Graph containing this Edge

See Also:

Edge.getGraph()

isDirected

public boolean isDirected()

Description copied from interface: Edge

Indicates if this edge is directed or undirected.

Specified by:

isDirected in interface Edge

Returns:

true if directed, false if undirected.

See Also:

Edge.isDirected()

getSourceNode

public Node getSourceNode()

Description copied from interface: Edge

Returns the first, or source, node upon which this Edge is incident.

Specified by:

getSourceNode in interface Edge

Returns:

the source Node

See Also:

Edge.getSourceNode()

getTargetNode

public Node getTargetNode()

Description copied from interface: Edge

Returns the second, or target, node upon which this Edge is incident.

Specified by:

getTargetNode in interface Edge

Returns:

the source Node

See Also:

Edge.getTargetNode()

getAdjacentNode

public Node getAdjacentNode(Node n)

Description copied from interface: Edge

Given a Node upon which this Edge is incident, the opposite incident Node is returned. Throws an exception if the input node is not incident on this Edge.

Specified by:

getAdjacentNode in interface Edge

Parameters:

n - a Node upon which this Edge is incident

Returns:

the other Node touched by this Edge

See Also:

Edge.getAdjacentNode(prefuse.data.Node)
