Method Detail

parseOperation

public org.openrdf.query.parser.ParsedOperation parseOperation(String operation,
                                                      String baseURI)
                                                        throws org.openrdf.query.MalformedQueryException

Parse either a SPARQL QUERY or a SPARQL UPDATE request.

Parameters:

operation - The request.

baseURI - The base URI.

Returns:

The ParsedOperation

Throws:

org.openrdf.query.MalformedQueryException

parseQuery

public BigdataParsedQuery parseQuery(String queryStr,
                            String baseURI)
                              throws org.openrdf.query.MalformedQueryException

The use of the alternative parseQuery2(String, String) is strongly encouraged.

Specified by:

parseQuery in interface org.openrdf.query.parser.QueryParser

Returns:

An object which aligns the ASTContainer with the ParsedQuery interface.

Throws:

org.openrdf.query.MalformedQueryException
