Interface Layerer

public interface Layerer

The hierarchic layout algorithms use this interface during the phase that assigns nodes to layers.

Implementations of this interface are responsible for partitioning the nodes of the input graph in hierarchic layers.

Method Summary

int	assignNodeLayer(LayoutGraph graph, NodeMap layerID, EdgeList reversedEdges) Assigns all nodes of the graph to layers.

Method Detail

assignNodeLayer

int assignNodeLayer(LayoutGraph graph,
                    NodeMap layerID,
                    EdgeList reversedEdges)

Assigns all nodes of the graph to layers.

Parameters:

graph - the given graph

layerID - the NodeMap that will be filled by the layout algorithm and returns the zero-based index of the layer to which each node belongs

reversedEdges - an EdgeList containing the edges which had been reversed

Returns:

the number of layers
