generateQueryKey

public static QueryKey generateQueryKey(String queryString,
                                        QueryParameters queryParameters,
                                        Set filterKeys,
                                        SharedSessionContractImplementor session,
                                        CacheableResultTransformer customTransformer)

Generates a QueryKey.
