y.layout.tree
Class FreePlacer

java.lang.Object
  y.layout.tree.AbstractRotatableNodePlacer
      y.layout.tree.FreePlacer

All Implemented Interfaces:

FromSketchNodePlacer, NodePlacer

public class FreePlacer
extends AbstractRotatableNodePlacer

Placer that can be used as simple "pseudo"-placer. May be useful if the localRoot does not have any children or you want to place them manually.

Method Detail

determineChildConnector

protected byte determineChildConnector(Node child)

Description copied from class: AbstractRotatableNodePlacer

This method must be implemented by subclasses. It is used to assigns a connector shape direction to each child.

Specified by:

determineChildConnector in class AbstractRotatableNodePlacer

Parameters:

child -

Returns:

NodePlacer.DIRECTION_NONE

placeSubtree

protected y.layout.tree.SubtreeShapeRotated placeSubtree(Node localRoot,
                                                         byte parentConnectorDirection)

Creates the subtree shape

Specified by:

placeSubtree in class AbstractRotatableNodePlacer

Parameters:

localRoot -

parentConnectorDirection -

Returns:

the created subtree shape

createProcessor

public Processor createProcessor(GenericTreeLayouter layouter,
                                 LayoutGraph graph,
                                 Node currentRoot)

Creates a processor suitable to the FreePlacer.
This processor will change all descendants node placers to FreePlacer.

Specified by:

createProcessor in interface NodePlacer

Overrides:

createProcessor in class AbstractRotatableNodePlacer

Parameters:

layouter -

graph -

currentRoot -

Returns:

a Processor or null
