Class RemoveOverlapsLayoutStage

java.lang.Object
  y.layout.organic.RemoveOverlapsLayoutStage

All Implemented Interfaces:

Layouter, LayoutStage

public class RemoveOverlapsLayoutStage
extends Object
implements LayoutStage

This LayoutStage removes node overlaps and guarantees a certain minimal node distance.

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.

Specified by:

canLayout in interface Layouter

doLayout

public void doLayout(LayoutGraph graph)

Assigns a new graph layout to the given layout graph.

Specified by:

doLayout in interface Layouter

updatePos

protected void updatePos()

updates arrays x and y according to the current centers of the nodes

getCoreLayouter

public Layouter getCoreLayouter()

Returns the core layouter.

Specified by:

getCoreLayouter in interface LayoutStage

setCoreLayouter

public void setCoreLayouter(Layouter l)

Sets the core layouter.

Specified by:

setCoreLayouter in interface LayoutStage
