Parameters:

valueFactory - The factory to use to create values.

Method Details

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.

getTupleQueryResultFormat

public TupleQueryResultFormat getTupleQueryResultFormat()

Description copied from interface: TupleQueryResultParser
