Method Detail

writeNode

public void writeNode(org.w3c.dom.Node node)
               throws 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:

IOException - if the write to underlying stream has failed

org.w3c.dom.DOMException - if used symbol table is read only and some of node's content can not be serialized.

compress

public static byte[] compress(org.w3c.dom.Node node,
                              SymbolTable symbols)

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
