Interface CompressedDocument

All Superinterfaces:

CompressedNode, org.w3c.dom.Document, org.w3c.dom.Node

All Known Implementing Classes:

DocumentImpl

public interface CompressedDocument

extends CompressedNode, org.w3c.dom.Document

CompressedDocument exposes the Document's SymbolTable.

Method Summary

org.w3c.dom.Node	getNodeAtPos(int pos) getNodeAtPos returns the Node that exists at the specified byte data position in the compressed stream.
SymbolTable	getSymbols() getSymbols returns the Symbol table for this Document.
void	setSymbols(SymbolTable symbols) setSymbols sets the Symbol table for this Document.

Method Detail

getSymbols

public SymbolTable getSymbols()

getSymbols returns the Symbol table for this Document. A new Document may not have a Symbol table as Symbol tables only come into play when a Document has been compressed or decompressed.

Returns:

The Symbol table

setSymbols

public void setSymbols(SymbolTable symbols)
                throws org.w3c.dom.DOMException

setSymbols sets the Symbol table for this Document. Setting the Symbol table for a Document that already has a Symbol table could be VERY BAD. Generally, an implementation should throw a DOMException if an attempt is made to reassign a Symbol table.

Parameters:

symbols - The Symbol table

Throws:

org.w3c.dom.DOMException - if an exception occurs

getNodeAtPos

public org.w3c.dom.Node getNodeAtPos(int pos)

getNodeAtPos returns the Node that exists at the specified byte data position in the compressed stream. This method should only be used on an unmodified Document as the underlying compressed stream of a document will become invalid as the Document is modified.

Parameters:

pos - The compressed stream position

Returns:

The Node (or null if not found)
