* Temporary state, used to reduce the occurrence of temporary garbage * while computing things such as bounds and transforms, and while * picking. Since these operations happen extremely often and must be * very fast, we need to reduce the load on the garbage collector. * *

Field Detail

bounds	back to summary
public BaseBounds bounds A temporary rect used for computing bounds by the various bounds variables. This bounds starts life as a RectBounds, but may be promoted to a BoxBounds if there is a 3D transform mixed into its computation.

leafTx	back to summary
public final Affine3D leafTx A temporary affine transform used by the path transition to avoid creating temporary garbage.

pickTx	back to summary
public final BaseTransform pickTx A temporary affine transform used when picking to avoid creating temporary garbage.

point	back to summary
public final Point2D point A temporary point used for picking and other purposes.

projViewTx	back to summary
public final GeneralTransform3D projViewTx A temporary general transform used by LOD helper method, in node, to compute area in scene.

private static final ThreadLocal<TempState> tempStateRef

tempTx	back to summary
public final Affine3D tempTx A temporary affine transform used by the LOD helper method to get an affine transform.
