public class Link
extends Leaf

A Link leaf node allows an application to reference a shared graph, rooted by a SharedGroup node, from within a branch graph or another shared graph. Any number of Link nodes can refer to the same SharedGroup node.

Field Summary

static int	ALLOW_SHARED_GROUP_READ For Link nodes, specifies that the node allows access to its object's SharedGroup information.
static int	ALLOW_SHARED_GROUP_WRITE For Link nodes, specifies that the node allows writing its object's SharedGroup information.

Constructor Summary

Link()
Constructs a Link node object that does not yet point to a SharedGroup node.

Link(SharedGroup sharedGroup)
Constructs a Link node object that points to the specified SharedGroup node.

Method Summary

Node	cloneNode(boolean forceDuplicate) Used to create a new instance of the node.
SharedGroup	getSharedGroup() Retrieves the node's SharedGroup reference.
void	setSharedGroup(SharedGroup sharedGroup) Sets the node's SharedGroup reference.

Constructor Detail

Link

public Link()

Constructs a Link node object that does not yet point to a SharedGroup node.

Link

public Link(SharedGroup sharedGroup)

Constructs a Link node object that points to the specified SharedGroup node.

Parameters:

sharedGroup - the SharedGroup node

Method Detail

setSharedGroup

public void setSharedGroup(SharedGroup sharedGroup)

Sets the node's SharedGroup reference.

Parameters:

sharedGroup - the SharedGroup node to reference

Throws:

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

getSharedGroup

public SharedGroup getSharedGroup()

Retrieves the node's SharedGroup reference.

Returns:

the SharedGroup node

Throws:

CapabilityNotSetException - if appropriate capability is not set and this object is part of live or 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.
The cloned Link node will refer to the same SharedGroup as the original node. The SharedGroup referred to by this Link node will not be cloned.

Overrides:

cloneNode in class 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.
