public class BassEdge
extends BassGraphElement

A BassEdge is an Object that describe the relation between two nodes. It stores the startNode (Band) and the endNode of a realtionship. Since mySpace only allow undirected graphs (a band/user can only be on another friendlist if that other band/user is on the own list) The Edge itself has a startNode a endNode and a vector who describes the direction of the edge. The Vector is calculated after the Layout algorithm did it's work.

Constructor Detail

BassEdge

public BassEdge()

empty constructor

BassEdge

public BassEdge(BassNode start,
                BassNode end)

Sets up an edge with the start node and the end node. Calls the setStart, setEnd methods. Those will add the edge to the node's internal edgelist

Parameters:

start -

end -

Method Detail

delete

public void delete()

Description copied from class: BassGraphElement

delete the specific element, removing all references to it. That is forever and can't be undone!

Specified by:

delete in class BassGraphElement

setStart

public void setStart(BassNode newStart)

Sets the startNode to an 'empty' bassedge object

Parameters:

newStart -

setEnd

public void setEnd(BassNode newEnd)

Sets the endNode to an 'empty' bassedge object

Parameters:

newEnd -

getStart

public BassNode getStart()

Returns:

the start node for this edge

getEnd

public BassNode getEnd()

Returns:

the end node for this edge

setVector

public void setVector(javax.vecmath.Vector3f v)

Set the vector for this edge to v

Parameters:

v -

getVector

public javax.vecmath.Vector3f getVector()

get the vector of this edge

Returns:

the vector of this edge
