public class TransformGroup

extends Group

ALLOW_TRANSFORM_READ

Specifies that the node allows access to its object's transform information.

ALLOW_TRANSFORM_WRITE

Specifies that the node allows writing its object's transform information.

TransformGroup()

Constructs and initializes a TransformGroup using an identity transform.

TransformGroup(Transform3D)

Constructs and initializes a TransformGroup from the Transform passed.

cloneNode(boolean)

Creates a new instance of the node.

duplicateNode(Node, boolean)

Copies all node information from originalNode into the current node.

getTransform(Transform3D)

Copies the transform component of this TransformGroup into the passed transform object.

setTransform(Transform3D)

Sets the transform component of this TransformGroup to the value of the passed transform.

 public static final int ALLOW_TRANSFORM_READ

Specifies that the node allows access to its object's transform information.

 public static final int ALLOW_TRANSFORM_WRITE

Specifies that the node allows writing its object's transform information.

 public TransformGroup()

Constructs and initializes a TransformGroup using an identity transform.

 public TransformGroup(Transform3D t1)

Constructs and initializes a TransformGroup from the Transform passed.

Parameters:

t1 - the transform3D object

Throws: BadTransformException

if the transform is not affine.

 public final void setTransform(Transform3D t1)

Sets the transform component of this TransformGroup to the value of the passed transform.

Parameters:

t1 - the transform to be copied.

Throws: CapabilityNotSetException

if appropriate capability is not set and this object is part of live or compiled scene graph

Throws: BadTransformException

if the transform is not affine.

 public final void getTransform(Transform3D t1)

Copies the transform component of this TransformGroup into the passed transform object.

Parameters:

t1 - the transform object to be copied into.

Throws: CapabilityNotSetException

if appropriate capability is not set and this object is part of live or compiled scene graph

 public Node cloneNode(boolean forceDuplicate)

Creates a new instance of the node. This routine is called by cloneTree to duplicate the current node.

Parameters:

forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.

Overrides:

cloneNode in class Group

 public void duplicateNode(Node originalNode,
                           boolean forceDuplicate)

Copies all node information from originalNode into the current node. This method is called from the cloneNode method which is, in turn, called by the cloneTree method.

For any NodeComponent objects contained by the object being duplicated, each NodeComponent object's duplicateOnCloneTree value is used to determine whether the NodeComponent should be duplicated in the new node or if just a reference to the current node should be placed in the new node. This flag can be overridden by setting the forceDuplicate parameter in the cloneTree method to true.

Parameters:

originalNode - the original node to duplicate.

forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.

Overrides:

duplicateNode in class Group

cloneNode, duplicateNode, cloneTree, setDuplicateOnCloneTree
