public Set<MediaType> getSupportedTypes(ParseContext context) {
        return parser.getSupportedTypes(context);
    }
Delegates the method call to the decorated parser. Subclasses should
override this method (and use <code>super.getSupportedTypes()</code>
to invoke the decorated parser) to implement extra decoration.
