Class GivenSequenceSequencer

java.lang.Object
  y.layout.hierarchic.incremental.GivenSequenceSequencer

All Implemented Interfaces:

Sequencer

public class GivenSequenceSequencer
extends Object
implements Sequencer

This LayerSequencer implementation returns a sequencing that satisfies a comparator constraint.

Constructor Summary

GivenSequenceSequencer()
Creates a new instance of GivenSequenceSequencer

GivenSequenceSequencer(Comparator c)
Creates a new instance of GivenSequenceSequencer using the specified comparator for the sequencing.

Method Summary

Comparator	getSequenceComparator() Returns the comparator used by this GivenSequenceSequencer.
void	sequenceNodeLayers(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Called by HierarchicLayouter during the second phase.
void	setSequenceComparator(Comparator sequenceComparator) Sets the comparator used by this GivenSequenceSequencer.

sequenceNodeLayers

public void sequenceNodeLayers(LayoutGraph graph,
                               Layers layers,
                               LayoutDataProvider ldp,
                               ItemFactory itemFactory)

Description copied from interface: Sequencer

Called by HierarchicLayouter during the second phase. Calculates a sequence of the nodes in layers and finally writes back the calculated sequence using the Layer.setNodeOrder(y.base.YList) method.

Specified by:

sequenceNodeLayers in interface Sequencer

Parameters:

graph - the graph that contains the elements from layers

layers - the Layer implementation that holds the Layers for sequencing

ldp - the LayoutDataProvider that provides the necessary NodeData and EdgeData

itemFactory - an ItemFactory implementation that can be used to modify the graph consistently
