All Implemented Interfaces:

Layouter, LayoutStage

public class RecursiveGroupLayouter

extends AbstractLayoutStage

Applies a given layout algorithm to each content of a group node recursively in bottom up fashion. The size of the group nodes is recursively determined using a configurable GroupBoundsCalculator instance. This class can be run withouth a core layouter instance. In this case the group node bounds will be adjusted in bottom-up fashion only.

RecursiveGroupLayouter

public RecursiveGroupLayouter(Layouter core,
                              GroupBoundsCalculator gpc)

Creates a new instance of RecursiveGroupLayouter

Method Detail

canLayout

public boolean canLayout(LayoutGraph graph)

Description copied from interface: Layouter

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

doLayout

public void doLayout(LayoutGraph graph)

Description copied from interface: Layouter

Assigns a new graph layout to the given layout graph.

getGroupBoundsCalculator

public GroupBoundsCalculator getGroupBoundsCalculator()

Returns the currently installed GroupBoundsCalculator instance

Returns:

the GroupBoundsCalculator instance.

setGroupBoundsCalculator

public void setGroupBoundsCalculator(GroupBoundsCalculator groupBoundsCalculator)

Sets the new GroupBoundsCalculator instance.

Parameters:

groupBoundsCalculator - New GroupBoundsCalculator instance.
