java.lang.Objectorg.eclipse.persistence.jpa.jpql.parser.DefaultJPQLGrammar
public final class DefaultJPQLGrammar
This JPQL grammar
provides support for parsing JPQL queries defined in the
latest JPA functional specification. The current version of the functional specification is
JSR-337 Java Persistence 2.0.
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.
