public abstract class ExpressionFactory extends Object implements Comparable<ExpressionFactory>
ExpressionFactory
is responsible to parse a portion of JPQL query which starts
with one of the factory's JPQL identifiers.
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.
