org.eclipse.persistence.jpa.jpql.model.BasicStateObjectBuilder
public abstract class BasicStateObjectBuilder
The default implementation of a IBuilder
, which creates a StateObject
representation of the Expression
being
visited.
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.
