y.layout.organic
Class GroupedShuffleLayouter

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.organic.GroupedShuffleLayouter

All Implemented Interfaces:

Layouter, LayoutStage

public class GroupedShuffleLayouter
extends AbstractLayoutStage

This class uses a customizable shuffle layout algorithm to recursively remove node overlaps from grouped graph structures. This class can be used as a LayoutStage in which case it will perform its work after the core layouter instance has performed its work.

Constructor Summary

GroupedShuffleLayouter()

GroupedShuffleLayouter(Layouter core)
Creates a new instance of GroupedShuffleLayouter The given core layouter instance will get to perform its work before the actual shuffling takes place.

Method Summary

boolean	canLayout(LayoutGraph graph) Returns true iff the given graph can be laid out by this algorithm.
void	doLayout(LayoutGraph graph) Main layout routine that assigns new layout information to the given graph.
GroupBoundsCalculator	getGroupBoundsCalculator() Returns the currently installed GroupBoundsCalculator instance
Layouter	getShuffleLayouter() Returns the layouter instance, that will be used for shuffling (removing node overlaps).
void	setGroupBoundsCalculator(GroupBoundsCalculator groupBoundsCalculator) Sets the new GroupBoundsCalculator instance.
void	setShuffleLayouter(Layouter shuffleLayouter) Sets the layouter instance, that will be used for shuffling (removing node overlaps).

GroupedShuffleLayouter

public GroupedShuffleLayouter(Layouter core)

Creates a new instance of GroupedShuffleLayouter The given core layouter instance will get to perform its work before the actual shuffling takes place.

Method Detail

canLayout

public boolean canLayout(LayoutGraph graph)

Description copied from interface: Layouter

Returns true iff the given graph can be laid out by this algorithm. Calling doLayout with the given graph as its argument will only success if this method returns true.

doLayout

public void doLayout(LayoutGraph graph)

Description copied from interface: Layouter

Main layout routine that assigns new layout information to the given graph.

getGroupBoundsCalculator

public GroupBoundsCalculator getGroupBoundsCalculator()

Returns the currently installed GroupBoundsCalculator instance

Returns:

the GroupBoundsCalculator instance.

setGroupBoundsCalculator

public void setGroupBoundsCalculator(GroupBoundsCalculator groupBoundsCalculator)

Sets the new GroupBoundsCalculator instance.

Parameters:

groupBoundsCalculator - New GroupBoundsCalculator instance.

getShuffleLayouter

public Layouter getShuffleLayouter()

Returns the layouter instance, that will be used for shuffling (removing node overlaps).

setShuffleLayouter

public void setShuffleLayouter(Layouter shuffleLayouter)

Sets the layouter instance, that will be used for shuffling (removing node overlaps).
