Class CollinearBendHider

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.router.CollinearBendHider

All Implemented Interfaces:

Layouter, LayoutStage

public class CollinearBendHider
extends AbstractLayoutStage

CollinearBendHider temporarily hides collinear bends on edge paths.

The bends are hidden before invoking the core layout algorith and reinserted afterwards. This may be necessary to keep an EdgeLayout fixed without having the collinear bends influencing the layout.

Field Summary

static java.lang.Object

SELECTED_EDGES A DataProvider key for selecting edges whose bends will be temporarily hidden If there is no DataProvider registered with this key, all edges are considered.

EDGE_ID_DPKEY, NODE_ID_DPKEY, NODE_TYPE_DPKEY, SELECTED_NODES

Constructor Summary

CollinearBendHider(Layouter coreLayouter)
Creates a new instance of CollinearBendHider using the given core layout algorithm.

Method Summary

boolean	canLayout(LayoutGraph graph) Accepts all general graphs.
void	doLayout(LayoutGraph graph) Hides collinear bends of the selected edges before invoking the core layout algorithm.

SELECTED_EDGES

public static final java.lang.Object SELECTED_EDGES

A DataProvider key for selecting edges whose bends will be temporarily hidden

If there is no DataProvider registered with this key, all edges are considered.

Constructor Detail

CollinearBendHider

public CollinearBendHider(Layouter coreLayouter)

Creates a new instance of CollinearBendHider using the given core layout algorithm.

Parameters:

coreLayouter - the core layout algorithm

Method Detail

canLayout

public boolean canLayout(LayoutGraph graph)

Accepts all general graphs.

Parameters:

graph - the input graph

Returns:

true for all input graphs

Layouter.doLayout(LayoutGraph)

doLayout

public void doLayout(LayoutGraph graph)

Hides collinear bends of the selected edges before invoking the core layout algorithm. The temporarily hidden bends are reinserted afterwards.

Parameters:

graph - the input graph
