public class DefaultGrammarValidator
This validator is responsible to validate a JPQL query grammatically purely based on the JPA specification document.
Provisional API: This interface is part of an interim API that is still under development and
expected to change significantly before reaching stability. It is available at this early stage
to solicit feedback from pioneering adopters on the understanding that any code that uses this
API will almost certainly be broken (repeatedly) as the API evolves.
