 protected GroupingNode()
empty constructor to prevent direct instantiation of this class.

o GroupingNode 
 protected GroupingNode(Browser b)
Constructor to pass the browser reference down to the base class

Parameters:
b - The browser reference to be passed on

Methods

o addChildren 
 public void addChildren(ChildrenNode child_list[])
Add the list of children to this node.

Parameters:
child_list - The children to add.
o removeChildren 
 public void removeChildren(ChildrenNode child_list[])
Remove the list of children to this node.

Parameters:
child_list - The children to remove.
o set_children 
 public void set_children(ChildrenNode child_list[])
Set the children field. This automatically deletes the previously set children and makes sure they are cleaned up properly.

Parameters:
child_list - The new children to set.
o get_children 
 public ChildrenNode[] get_children()
Get the current children

Returns:
The list of currently set children.
o get_bboxCenter 
 public float[] get_bboxCenter()
Get the bounding box center position.

Returns:
The center postion where return[0] = x, return[1] = y, return[2] = z
o get_bboxSize 
 public float[] get_bboxSize()
Get the bounding box size position.

Returns:
The size where return[0] = x, return[1] = y, return[2] = z
o writeReset 
 public void writeReset()
Used for maintaining the reference counting when trying to do DEF/USE in the write to stream method.

Overrides:
