y.layout
Class MinNodeSizeStage

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.MinNodeSizeStage

All Implemented Interfaces:

Layouter, LayoutStage

public class MinNodeSizeStage
extends AbstractLayoutStage

This layout stage enforces a given minimum width/height of the nodes of a graph during the layout process. Therefore it temporarily enlarges nodes whose width/height fall below the specified minimum values.

EDGE_ID_DPKEY, NODE_ID_DPKEY, SELECTED_EDGES, SELECTED_NODES

Constructor Summary

MinNodeSizeStage(Layouter core)
Instantiates a new MinNodeSizeStage that wraps the given core layouter.

MinNodeSizeStage(Layouter core, double minWidth, double minHeight)
Instantiates a new MinNodeSizeStage that wraps the given core layouter.

Method Summary

boolean	canLayout(LayoutGraph graph) Returns true iff the given graph can be laid out by this algorithm.
void	doLayout(LayoutGraph graph) Main layout routine that assigns new layout information to the given graph.

Constructor Detail

MinNodeSizeStage

public MinNodeSizeStage(Layouter core,
                        double minWidth,
                        double minHeight)

Instantiates a new MinNodeSizeStage that wraps the given core layouter.

Parameters:

core - The core layouter.

minWidth - The minimum width of nodes that should be enforced.

minHeight - The minimum height of nodes that should be enforced.

MinNodeSizeStage

public MinNodeSizeStage(Layouter core)

Instantiates a new MinNodeSizeStage that wraps the given core layouter. The minimum width/height of nodes is set to 1.

Parameters:

core - The core layouter.

Method Detail

canLayout

public boolean canLayout(LayoutGraph graph)

Description copied from interface: Layouter

Returns true iff the given graph can be laid out by this algorithm. Calling doLayout with the given graph as its argument will only success if this method returns true.

doLayout

public void doLayout(LayoutGraph graph)

Description copied from interface: Layouter

Main layout routine that assigns new layout information to the given graph.
