public void writeNode(org.w3c.dom.Node node)
               throws java.io.IOException

writeNode writes a Node to the compressed output stream. This method is recursive and will write all children of the specific Node.

Parameters:

node - The Node to write

Throws:

java.io.IOException - If the write failed

Compress

public static byte[] Compress(org.w3c.dom.Node node,
                              SymbolTable symbols)
                       throws org.dbxml.server.dbXMLException

Compress is a convenience method that compresses a Node into a byte array with a single call.

Parameters:

node - The Node to compress

symbols - The Symbol Table to use

Returns:

The resulting byte array

Throws:

org.dbxml.server.dbXMLException - if an Exception occurs
