Interface HqlTranslator

@Incubating(since="8.0") @SPI({IMPLEMENT,SUPPLY}) public interface HqlTranslator

Global integration contract for translating HQL or JPQL text to SQM.

This is not a database Dialect contract. Framework integrations may supply one translator through QueryEngineOptions; the resulting instance is normally shared by the query engine and must therefore be thread-safe. Implementations must produce a fresh semantic statement for each invocation and must not infer database syntax.
