parseQueryResult

public void parseQueryResult(InputStream in)
                      throws IOException,
                             QueryResultParseException,
                             QueryResultHandlerException

Description copied from interface: QueryResultParser

Parse the query results out of the given InputStream into the handler setup using QueryResultParser.setQueryResultHandler(QueryResultHandler).

Parameters:

in - The InputStream to parse the results from.

Throws:

IOException - If there is an exception from the InputStream.

QueryResultParseException - If the query results are not parsable by this parser.

QueryResultHandlerException - If the QueryResultHandler set in QueryResultParser.setQueryResultHandler(QueryResultHandler) throws an exception.

parseQueryResultInternal

protected boolean parseQueryResultInternal(InputStream in,
                                           boolean attemptParseBoolean,
                                           boolean attemptParseTuple)
                                    throws IOException,
                                           QueryResultParseException,
                                           QueryResultHandlerException

Throws:

IOException
