Modifies the underlying Unmarshaller to only accept Content-Types matching one of the given ranges.
Modifies the underlying Unmarshaller to only accept Content-Types matching one of the given ranges. Note that you can only restrict to a subset of the Content-Types accepted by the underlying unmarshaller, i.e. the given ranges must be completely supported also by the underlying Unmarshaller! If a violation of this rule is detected at runtime, i.e. if an entity is encountered whose Content-Type is matched by one of the given ranges but rejected by the underlying unmarshaller an IllegalStateException will be thrown!
