com.fasterxml.jackson.databind.deser.Deserializers
Interface that defines API for simple extensions that can provide additional deserializers for various types. Access is by a single callback method; instance is to either return a configured {@link JsonDeserializer} for specified type, or null to indicate that itdoes not support handling of the type. In latter case, further calls can be made for other providers; in former case returned deserializer is used for handling of instances of specified type.
Unlike with {@link com.fasterxml.jackson.databind.ser.Serializers}, multiple different methods are used since different kinds of types typically require different kinds of inputs.

      public Void execute(RequestInfo request, int counter) {
        return provider.provideForRequest(request, new Execution<Void>() {


          public Void insideRequest(Container container) {
            Deserializers deserializers = container.instanceFor(Deserializers.class);
            assertNotNull(deserializers.deserializerFor("application/json", container));
            assertNotNull(deserializers.deserializerFor("json", container));
            assertNotNull(deserializers.deserializerFor("application/xml", container));
            assertNotNull(deserializers.deserializerFor("xml", container));
            assertNotNull(deserializers.deserializerFor("text/xml", container));
            assertNotNull(deserializers.deserializerFor("application/x-www-form-urlencoded", container));
            return null;
          }


        });
