Method Detail

isDirected

public boolean isDirected()

Returns true, if the Edge is directed, false otherwise.

Specified by:

isDirected in interface Edge

Returns:

true, if the Edge is directed, false otherwise.

getSource

public Node getSource()

Returns the source of the Edge.

Specified by:

getSource in interface Edge

Returns:

the source of the Edge.

getTarget

public Node getTarget()

Returns the target of the Edge.

Specified by:

getTarget in interface Edge

Returns:

the target of the Edge.

doSetTarget

public void doSetTarget(Node target)
                 throws GraphElementNotFoundException,
                        IllegalArgumentException

Sets the target of the current Edge to target. Target must be contained in the same Graph as the Edge. Informs the ListenerManager about the change.

Parameters:

target - the target to be set.

Throws:

GraphElementNotFoundException - if the target cannot be found in the Graph.

IllegalArgumentException - if target is not of type AdjListNode.
