public interface Layout<V,E>
extends org.apache.commons.collections15.Transformer<V,Point2D>

A generalized interface is a mechanism for returning (x,y) coordinates from vertices. In general, most of these methods are used to both control and get information from the layout algorithm.

Method Summary

Graph<V,E>	getGraph() Returns the full graph (the one that was passed in at construction time) that this Layout refers to.
Dimension	getSize() Returns the current size of the visualization's space.
void	initialize() Initializes fields in the node that may not have been set during the constructor.
boolean	isLocked(V v) Returns true if the position of vertex v is locked.
void	lock(V v, boolean state) Sets a flag which fixes this vertex in place.
void	reset()
void	setGraph(Graph<V,E> graph) setter for graph
void	setInitializer(org.apache.commons.collections15.Transformer<V,Point2D> initializer) provides initial locations for all vertices.
void	setLocation(V v, Point2D location) set the location of a vertex
void	setSize(Dimension d)

Method Detail

initialize

void initialize()

Initializes fields in the node that may not have been set during the constructor. Must be called before the iterations begin.

setInitializer

void setInitializer(org.apache.commons.collections15.Transformer<V,Point2D> initializer)

provides initial locations for all vertices.

Parameters:

initializer -

setGraph

void setGraph(Graph<V,E> graph)

setter for graph

Parameters:

graph -

getGraph

Graph<V,E> getGraph()

Returns the full graph (the one that was passed in at construction time) that this Layout refers to.

reset

void reset()

setSize

void setSize(Dimension d)

Parameters:

d -

getSize

Dimension getSize()

Returns the current size of the visualization's space.

lock

void lock(V v,
          boolean state)

Sets a flag which fixes this vertex in place.

Parameters:

v - vertex

isLocked

boolean isLocked(V v)

Returns true if the position of vertex v is locked.

setLocation

void setLocation(V v,
                 Point2D location)

set the location of a vertex

Parameters:

v -

location -
