Class RemoveColinearBendsStage

java.lang.Object
  y.layout.AbstractLayoutStage
      y.layout.RemoveColinearBendsStage

All Implemented Interfaces:

Layouter, LayoutStage

public class RemoveColinearBendsStage
extends AbstractLayoutStage

This LayoutStage removes all collinear bends found in the graph. If three bends with the same X- or Y-value are found, the bend in the middle is removed.

Method Summary

boolean	canLayout(LayoutGraph graph) Returns true iff the given graph can be laid out by this algorithm.
void	doLayout(LayoutGraph graph) Removes collinear bends of the edges.

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 it's argument will only success if this method returns true.

getScale

public double getScale()

Returns the current scale, to which this stage will refer, when checking for collinearity. Default value is 2.0. Which means that values are rounded to the second position after the decimal point. If the rounded values of an edge are leading to a collinear bend, this bend will be removed.

Returns:

the current scale to which this stage will refer, when checking for collinearity.

setScale

public void setScale(double scale)

Sets the current scale, to which this stage will refer, when checking for collinearity. Default value is 2.0. Which means that values are rounded to the second position after the decimal point. If the rounded values of an edge are leading to a collinear bend, this bend will be removed.

Parameters:

scale - the current scale to which this stage will refer, when checking for collinearity.

doLayout

public void doLayout(LayoutGraph graph)

Removes collinear bends of the edges.

Parameters:

graph -
