ROS_CREATE_SIMPLE_SERIALIZER

#define ROS_CREATE_SIMPLE_SERIALIZER

(

Type

)

Value:

template<> struct Serializer<Type> \
  { \
    template<typename Stream> inline static void write(Stream& stream, const Type v) \
    { \
      memcpy(stream.advance(sizeof(v)), &v, sizeof(v) ); \
    } \
    \
    template<typename Stream> inline static void read(Stream& stream, Type& v) \

    } \
    \
    inline static uint32_t serializedLength(const Type&) \
      { \
      return sizeof(Type); \
    } \
};

ROS_DECLARE_ALLINONE_SERIALIZER

#define ROS_DECLARE_ALLINONE_SERIALIZER

Value:

template<typename Stream, typename T> \
  inline static void write(Stream& stream, const T& t) \
  { \
    allInOne<Stream, const T&>(stream, t); \
  } \
  \
  template<typename Stream, typename T> \
  inline static void read(Stream& stream, T& t) \
  { \
    allInOne<Stream, T&>(stream, t); \
  } \
  \
  template<typename T> \
  inline static uint32_t serializedLength(const T& t) \
  { \
    LStream stream; \
    allInOne<LStream, const T&>(stream, t); \
    return stream.getLength(); \
  }

Declare your serializer to use an allInOne member instead of requiring 3 different serialization functions.

The allinone method has the form:

template<typename Stream, typename T>
inline static void allInOne(Stream& stream, T t)
{
  stream.next(t.a);
  stream.next(t.b);
  ...
}

The only guarantee given is that Stream::next(T) is defined.
