public class Resolver<T>
extends java.lang.Object

A resolver resolves objects of various types to a single type. This base implementation simply checks if objects are instances of the type to resolve to, and returns the object cast to the type if that is the case.

Instances of Callable and Supplier are handled by recursively resolving the object returned from the call or get method.
