createQueryTranslator

public QueryTranslator createQueryTranslator(String queryIdentifier,
                                             String queryString,
                                             Map filters,

                                             EntityGraphQueryHint entityGraphQueryHint)

Description copied from interface: QueryTranslatorFactory

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

Specified by:

createQueryTranslator in interface QueryTranslatorFactory

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.
