Class Link

    java.lang.Object
      javax.media.j3d.SceneGraphObject
          javax.media.j3d.Node

    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.

Fields inherited from class javax.media.j3d.Node
`ALLOW_AUTO_COMPUTE_BOUNDS_READ, ALLOW_AUTO_COMPUTE_BOUNDS_WRITE, ALLOW_BOUNDS_READ, ALLOW_BOUNDS_WRITE, ALLOW_COLLIDABLE_READ, ALLOW_COLLIDABLE_WRITE, ALLOW_LOCAL_TO_VWORLD_READ, ALLOW_LOCALE_READ, ALLOW_PARENT_READ, ALLOW_PICKABLE_READ, ALLOW_PICKABLE_WRITE, ENABLE_COLLISION_REPORTING, ENABLE_PICK_REPORTING`

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.

Field Detail

### ALLOW_SHARED_GROUP_READ

    public static final int ALLOW_SHARED_GROUP_READ

  For Link nodes, specifies that the node allows access to its object's SharedGroup information.

    Constant Field Values

### ALLOW_SHARED_GROUP_WRITE

    public static final int ALLOW_SHARED_GROUP_WRITE

  For Link nodes, specifies that the node allows writing its object's SharedGroup information.

  See Also:
    Constant Field Values

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.
  See Also:
    `Node.cloneTree()`, `Node.cloneNode(boolean)`, `Node.duplicateNode(javax.media.j3d.Node, boolean)`, `NodeComponent.setDuplicateOnCloneTree(boolean)`
