Method Detail

init

public 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.

Specified by:

init in interface Tuple<TableEdge>

Overrides:

init in class TableTuple<TableEdge>

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<?,TableNode,TableEdge> getGraph()

Description copied from interface: Edge

Returns the graph of which this Edge is a member.

Specified by:

getGraph in interface Edge<TableNode,TableEdge>

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<TableNode,TableEdge>

Returns:

true if directed, false if undirected.

See Also:

Edge.isDirected()

getSourceNode

public TableNode getSourceNode()

Description copied from interface: Edge

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

Specified by:

getSourceNode in interface Edge<TableNode,TableEdge>

Returns:

the source Node

See Also:

Edge.getSourceNode()

getTargetNode

public TableNode getTargetNode()

Description copied from interface: Edge

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

Specified by:

getTargetNode in interface Edge<TableNode,TableEdge>

Returns:

the source Node

See Also:

Edge.getTargetNode()

getAdjacentNode

public TableNode getAdjacentNode(TableNode 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<TableNode,TableEdge>

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)
