Method Detail

createQueryTranslator

QueryTranslator createQueryTranslator(String queryIdentifier,
                                      String queryString,

                                      SessionFactoryImplementor factory)

Construct a QueryTranslator instance capable of translating an HQL query string.

Parameters:

queryIdentifier - The query-identifier (used in QueryStatistics collection). This is typically the same as the queryString parameter except for the case of split polymorphic queries which result in multiple physical sql queries.

queryString - The query string to be translated

filters - Currently enabled filters

factory - The session factory.

Returns:

an appropriate translator.

                                        String queryString,
                                        Map filters,
