AbstractRotatableNodePlacer

public static class AbstractRotatableNodePlacer.Matrix
extends java.lang.Object

A matrix describes the rotation of the subtree handled by AbstractRotatableNodePlacer.

Subtrees may be rotated or mirrored. Also, matrices offering a combination of rotation and mirroring are provided.

static AbstractRotatableNodePlacer.Matrix	MIR_HOR A matrix which applies a horizontal mirroring.
static AbstractRotatableNodePlacer.Matrix	MIR_HOR_ROT90 A matrix which applies a horizontal mirroring and a counter-clockwise rotation by 90 degrees.
static AbstractRotatableNodePlacer.Matrix	MIR_VERT A matrix which applies a vertical mirroring.
static AbstractRotatableNodePlacer.Matrix	MIR_VERT_ROT90 A matrix which applies a vertical mirroring and a counter-clockwise rotation by 90 degrees.
static AbstractRotatableNodePlacer.Matrix	ROT180 A matrix which applies a rotation by 180 degrees.
static AbstractRotatableNodePlacer.Matrix	ROT270 A matrix which applies a counter-clockwise rotation by 270 degrees.
static AbstractRotatableNodePlacer.Matrix	ROT90 A matrix which applies a counter-clockwise rotation by 90 degrees.
