      public interface ContextResolver<T>

  Contract for a provider that supplies context information to resource classes and other providers. A `ContextResolver` implementation may be annotated with `Produces` to restrict the media types for which it will be considered suitable.

  Providers implementing `ContextResolver` contract must be either programmatically registered in a JAX-RS runtime or must be annotated with `@Provider` annotation to be automatically discovered by the JAX-RS runtime during a provider scanning phase.
