|
|
* NAME
|
|
* BufferNode -- Class to maintain the tree of bufferred elements
|
|
*
|
|
* FUNCTION
|
|
* One BufferNode object represents a bufferred element in the document
|
|
* wrapper component.
|
|
* All BufferNode objects construct a tree which has the same structure
|
|
* of all bufferred elements. That is to say, if one bufferred element is
|
|
* an ancestor of another bufferred element, then the corresponding
|
|
* BufferNode objects are also in ancestor/descendant relationship.
|
|
* This class is used to manipulate the tree of bufferred elements.
|
|
*
|
|
* HISTORY
|
|
* 05.01.2004 - implemented
