public interface Expression
This is the root interface of the parsed tree representation of a JPQL query. The way a JPQL query is parsed is based on the JPQL grammar used.

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.
