Method Detail

getQueryResultFormat

public QueryResultFormat getQueryResultFormat()

Description copied from interface: QueryResultParser

Gets the query result format that this parser can parse.

Specified by:

getQueryResultFormat in interface QueryResultParser

Returns:

The QueryResultFormat supported by this parser.

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).

Specified by:

parseQueryResult in interface QueryResultParser

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.

setTupleQueryResultHandler

public void setTupleQueryResultHandler(TupleQueryResultHandler handler)

Description copied from interface: TupleQueryResultParser

Sets the TupleQueryResultHandler that will handle the parsed query result data.

Specified by:

setTupleQueryResultHandler in interface TupleQueryResultParser
