public class SpringLayout2<V,E>
extends SpringLayout<V,E>

The SpringLayout package represents a visualization of a set of nodes. The SpringLayout, which is initialized with a Graph, assigns X/Y locations to each node. When called relax(), the SpringLayout moves the visualization forward one step.

Constructor Detail

SpringLayout2

public SpringLayout2(Graph<V,E> g)

Constructor for a SpringLayout for a raw graph with associated dimension--the input knows how big the graph is. Defaults to the unit length function.

Parameters:

g - the graph on which the layout algorithm is to operate

SpringLayout2

public SpringLayout2(Graph<V,E> g,
                     com.google.common.base.Function<E,java.lang.Integer> length_function)

Constructor for a SpringLayout for a raw graph with associated component.

Parameters:

g - the Graph to lay out

length_function - provides a length for each edge

Overrides:

step in class SpringLayout<V,E>

done

public boolean done()

Specified by:

done in interface IterativeContext

Overrides:

done in class SpringLayout<V,E>

Returns:

false
