Class AsIsSequencer

java.lang.Object

com.yworks.yfiles.layout.hierarchic.AsIsSequencer

All Implemented Interfaces:

ISequencer

public class AsIsSequencer
extends Object
implements ISequencer

This class calculates the sequence of the nodes within each layer using the nodes' coordinates.

For layout orientation LayoutOrientation.TOP_TO_BOTTOM, the order corresponds to that obtain when sorting the nodes according to their x-coordinate.

An instance of this class can be set to HierarchicLayout using method FixedElementsSequencer and FromScratchSequencer respectively.

Initial graph that will be used as sketch Hierarchic layout when the initial graph is used as sketch

Method Detail

sequenceNodeLayers

public void sequenceNodeLayers(LayoutGraph graph,
                               ILayers layers,
                               ILayoutDataProvider ldp,
                               IItemFactory itemFactory)

Calculates the sequence of the nodes within each layer using the nodes' coordinates.

This method is called by HierarchicLayoutCore and finally writes back the calculated sequence using method ILayer.setNodeOrder(YList).

Specified by:

sequenceNodeLayers in interface ISequencer

Parameters:

graph - the input graph

layers - the given ILayers instance that defines the layering structure

ldp - the ILayoutDataProvider containing information about the nodes and edges of the graph

itemFactory - the IItemFactory used for creating and destroying helper structures
