Interface LayerSequencer

All Known Implementing Classes:

ClassicLayerSequencer

public interface LayerSequencer

Classes implementing this interface calculate the order of nodes within the different layers that the graph has been partitioned into.

Method Summary

NodeList[]

getLayers(LayoutGraph g, NodeMap layerID, int maxLayer) Calculates the sequence of nodes within each layer.

Method Detail

getLayers

NodeList[] getLayers(LayoutGraph g,
                     NodeMap layerID,
                     int maxLayer)

Calculates the sequence of nodes within each layer.

Parameters:

g - the graph being acted upon

layerID - provides for each node an integral number signifying the layer of that node. The first layer has the number 0.

maxLayer - the number of different layers

Returns:

an array of length maxLayer containing node lists. Each node list contains the nodes of a corresponding layer. The order of the nodes within each node list represents the sequence of the nodes within their layer.
