/**
* An Adapter implementation of the
* {@link JwtHandler} interface that allows for anonymous subclasses to process only the JWT results that are
* known/expected for a particular use case.
*
* All of the methods in this implementation throw exceptions: overridden methods represent
* scenarios expected by calling code in known situations. It would be unexpected to receive a JWT that did
* not match parsing expectations, so all non-overridden methods throw exceptions to indicate that the JWT
* input was unexpected.
*
* @param the type of object to return to the parser caller after handling the parsed JWT.
* @since 0.2
