public abstract class AbstractGrammarValidator
extends AbstractValidator

The base validator responsible to gather the problems found in a JPQL query by validating it against the provided JPQL grammar. The semantic of the JPQL query is not validated by this visitor.

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.
