Method Detail

getGraph

Graph getGraph()

Get the graph of this node.

Returns:

The graph of this node.

getContextNode

ContextNode getContextNode()

Every node has a parent context node, except the root context node.

Returns:

The parent context node of this node, or null.

getContextNode

ContextNode getContextNode(int arcs)

Every node has ancestor context nodes, except the root context node.

Parameters:

arcs - The number of arcs to follow up the graph.

Returns:

The ancestor context node of this node, or null.

getXDIAddress

XDIAddress getXDIAddress()

Gets the address of this node. This returns the empty string for the root context node.

Returns:

The address of this node.

getXDIArc

XDIArc getXDIArc()

Every node has an associated arc. This returns null for the root context node.

Returns:

The arc associated with this node.

delete

void delete()

Deletes this node.
