- All Implemented Interfaces:
JPQLGrammar
public final class DefaultEclipseLinkJPQLGrammar extends java.lang.Object implements JPQLGrammar
ThisJPQL grammarprovides support for parsing JPQL queries defined by the JPA 2.1 functional specification and the EclipseLink 2.6.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.
