Constructor Details

SPARQLResultsJSONParser

public SPARQLResultsJSONParser()

Default constructor.

SPARQLResultsJSONParser

public SPARQLResultsJSONParser(ValueFactory valueFactory)

Construct a parser with a specific ValueFactory.

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

Gets the query result format that this parser can parse.

Specified by:

getTupleQueryResultFormat in interface TupleQueryResultParser

setTupleQueryResultHandler

@Deprecated
public void setTupleQueryResultHandler(TupleQueryResultHandler handler)

Deprecated.

Description copied from interface: TupleQueryResultParser

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

Specified by:

parse

@Deprecated
public void parse(InputStream in)
           throws IOException,
QueryResultParseException,
TupleQueryResultHandlerException

Deprecated.

Description copied from interface: TupleQueryResultParser

Parses the data from the supplied InputStream.

Specified by:

parse in interface TupleQueryResultParser

Parameters:

in - The InputStream from which to read the data.

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.
