getResponseXML

public final SimpleDocument getResponseXML()

reset

protected void reset()

Description copied from class: AsyncHttpRequest

Clears any response state and resets the readyState to UNINITIALIZED. Any overriding implementations MUST call super.reset() at the end of the implementation.

Overrides:

reset in class AsyncHttpRequest

handleResponse

protected void handleResponse(String responseText)
                       throws Exception

Description copied from class: AsyncHttpRequest

Method that provides a hook for subclasses to create concrete types (such as DOM, JSONObject, etc) when the response has been fully read. There is no need to call super.handleResponse(txt).

Overrides:

handleResponse in class AsyncHttpRequest

Throws:

Exception

printDocument

public static void printDocument(Document doc,
 OutputStream out)
                          throws IOException,
TransformerException

Throws:
