Class TempState

java.lang.Object

com.sun.javafx.util.TempState

public final class TempState
extends Object

* 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

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.

pickTx

public final BaseTransform pickTx

A temporary affine transform used when picking to avoid creating temporary garbage.

leafTx

public final Affine3D leafTx

A temporary affine transform used by the path transition to avoid creating temporary garbage.

point

public final Point2D point

A temporary point used for picking and other purposes.

vec3d

public final Vec3d vec3d

projViewTx

public final GeneralTransform3D projViewTx

A temporary general transform used by LOD helper method, in node, to compute area in scene.

tempTx

public final Affine3D tempTx

A temporary affine transform used by the LOD helper method to get an affine transform.
