* NAME
|
|
* BufferNode -- Class to maintain the tree of buffered elements
|
|
*
|
|
* FUNCTION
|
|
* One BufferNode object represents a buffered element in the document
|
|
* wrapper component.
|
|
* All BufferNode objects construct a tree which has the same structure
|
|
* of all buffered elements. That is to say, if one buffered element is
|
|
* an ancestor of another buffered element, then the corresponding
|
|
* BufferNode objects are also in ancestor/descendant relationship.
|
|
* This class is used to manipulate the tree of buffered elements.
