 * Base class for parameter resolvers using static types.

 * This is best suited if you want a simple resolver for a specific type, such as [TimeUnit] for example.
 *
 * Your implementation needs to be annotated with [@Resolver][Resolver],
 * unless this is an output of a [ParameterResolverFactory].
 *
 * @param T Type of the implementation
 * @param R Type of the returned resolved objects
