Method Detail

getSourceItem

NodeItem getSourceItem()

Get the first, or source, NodeItem upon which this edge is incident.

Returns:

the source NodeItem

getTargetItem

NodeItem getTargetItem()

Get the second, or target, NodeItem upon which this edge is incident.

Returns:

the target NodeItem

getAdjacentItem

NodeItem getAdjacentItem(NodeItem n)

Get the NodeItem connected to the given NodeItem by this edge.

Parameters:

n - a NodeItem upon which this edge is incident. If this item is not connected to this edge, a runtime exception will be thrown.

Returns:

the other NodeItem connected to this edge
