Interface ResolverVisitor

public interface ResolverVisitor

The interface is used to traverse some of the subclasses of Resolver. This visitor is meant to traverse state field path expressions and collection-valued path expressions. The hierarchy of resolving a path expression looks like this:

 EntityResolver
 or
 CollectionValuedFieldResolver
 or
 TreatResolver
  |
  -> IdentificationVariableResolver
      |
      (optional KeyResolver or ValueResolver)
      |
      -> StateFieldResolver
          |
        1...n
          |
          -> StateFieldResolver or CollectionValuedFieldResolver

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.
