Interface Sequencer

All Known Implementing Classes:

AsIsSequencer, DefaultLayerSequencer, GivenSequenceSequencer

public interface Sequencer

This interface is used by HierarchicLayouter to calculate the order of the nodes within each layer.

Implementations are used during the second phase of the hierarchic layout process and can be set using method IncrementalHierarchicLayouter.setFixedElementsSequencer(Sequencer) or IncrementalHierarchicLayouter.setFromScratchSequencer(Sequencer)).

Method Summary

void	sequenceNodeLayers(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Calculates the sequence of the nodes within each layer.

Method Detail

sequenceNodeLayers

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

Calculates the sequence of the nodes within each layer.

This method is called by HierarchicLayouter during the second phase and finally writes back the calculated sequence using the Layer.setNodeOrder(y.base.YList) method.

Parameters:

graph - the input graph

layers - the given Layers instance containing the elements in the layering

ldp - the LayoutDataProvider implementation which provides access to the NodeData and EdgeData instances

itemFactory - the ItemFactory used temporarily for modifying the graph instance
