Method Details

setRandomPosition

protected void setRandomPosition(Node nodeTemp,
 Random rnd)

Specified by:

setRandomPosition in class ForceBasedLayout

computeForce

protected void computeForce(Edge e,
 Vector2f force)

Description copied from class: ForceBasedLayout

Computes the force contribution of an edge. This method is invoked for every edge of the graph.

Specified by:

computeForce in class ForceBasedLayout

Parameters:

e - an edge

force - the force in the direction from edge.source to edge.target has to be placed in here

computeForce

protected void computeForce(Node s,
 Node t,
 Vector2f force)

Description copied from class: ForceBasedLayout

Computes the force contribution of a pair of nodes. This method is invoked for every pair of nodes, whether they are connected or not. The computed force should be anti-symmetric with respect to s and t, i.e., if these parameters are exchanged, the resulting force should be the negative of the original force.

Specified by:

computeForce in class ForceBasedLayout

Parameters:

s - the source node

t - the target node

force - the force in the direction from s to t has to be placed in here

getManageableType

public ManageableType getManageableType()
