Constructor Summary

SharedGroup()
Constructs and initializes a new SharedGroup node object.

Method Summary

Node	cloneNode(boolean forceDuplicate) Used to create a new instance of the node.
void	compile() Compiles the source SharedGroup associated with this object and creates and caches a compiled scene graph.
void	duplicateNode(Node originalNode, boolean forceDuplicate) Copies all node information from originalNode into the current node.

Constructor Detail

SharedGroup

public SharedGroup()

Constructs and initializes a new SharedGroup node object.

Method Detail

compile

public final void compile()

Compiles the source SharedGroup associated with this object and creates and caches a compiled scene graph.

cloneNode

public Node cloneNode(boolean forceDuplicate)

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

Overrides:

cloneNode in class Group

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.

See Also:

Node.cloneTree(), Node.cloneNode(boolean), Node.duplicateNode(javax.media.j3d.Node, boolean), NodeComponent.setDuplicateOnCloneTree(boolean)

duplicateNode

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.

Overrides:

duplicateNode in class Group

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.
