◆ COMPACTSIZE

#define COMPACTSIZE (   obj)    Using<CompactSizeFormatter<true>>(obj)

Definition at line 597 of file serialize.h.

◆ FORMATTER_METHODS

#define FORMATTER_METHODS (   cls,
  obj 
)
Value:
template <typename Stream> static void Ser(Stream &s, const cls &obj) { \
SerializationOps(obj, s, CSerActionSerialize()); \
} \
template <typename Stream> static void Unser(Stream &s, cls &obj) { \
SerializationOps(obj, s, CSerActionUnserialize()); \
} \
template <typename Stream, typename Type, typename Operation> \
static inline void SerializationOps(Type &obj, Stream &s, \
Operation ser_action)

Implement the Ser and Unser methods needed for implementing a formatter (see Using below).

Both Ser and Unser are delegated to a single static method SerializationOps, which is polymorphic in the serialized/deserialized type (allowing it to be const when serializing, and non-const when deserializing).

Example use: struct FooFormatter { FORMATTER_METHODS(Class, obj) { READWRITE(obj.val1, VARINT(obj.val2)); } } would define a class FooFormatter that defines a serialization of Class objects consisting of serializing its val1 member using the default serialization, and its val2 member using VARINT serialization. That FooFormatter can then be used in statements like READWRITE(Using<FooFormatter>(obj.bla)).

◆ SERIALIZE_METHODS

#define SERIALIZE_METHODS (   cls,

)
Value:
template <typename Stream> void Serialize(Stream &s) const { \
static_assert(std::is_same<const cls &, decltype(*this)>::value, \
"Serialize type mismatch"); \
Ser(s, *this); \
} \

static_assert(std::is_same<cls &, decltype(*this)>::value, \
"Unserialize type mismatch"); \
Unser(s, *this); \
} \
FORMATTER_METHODS(cls, obj)

Implement the Serialize and Unserialize methods by delegating to a single templated static method that takes the to-be-(de)serialized object as a parameter.

This approach has the advantage that the constness of the object becomes a template parameter, and thus allows a single implementation that sees the object as const for serializing and non-const for deserializing, without casts.

◆ VarIntMode

Variable-length integers: bytes are a MSB base-128 encoding of the number.

The high bit in each byte signifies whether another digit follows. To make sure the encoding is one-to-one, one is subtracted from all but the last digit. Thus, the byte sequence a[] with length len, where all but the last byte has bit 128 set, encodes the number:

(a[len-1] & 0x7F) + sum(i=1..len-1, 128^i*((a[len-i-1] & 0x7F)+1))

Properties:

  • Very small (0-127: 1 byte, 128-16511: 2 bytes, 16512-2113663: 3 bytes)
  • Every integer has exactly one encoding
  • Encoding does not depend on size of original integer type
  • No redundancy: every (infinite) byte sequence corresponds to a list of encoded integers.

0: [0x00] 256: [0x81 0x00] 1: [0x01] 16383: [0xFE 0x7F] 127: [0x7F] 16384: [0xFF 0x00] 128: [0x80 0x00] 16511: [0xFF 0x7F] 255: [0x80 0x7F] 65535: [0x82 0xFE 0x7F] 2^32: [0x8E 0xFE 0xFE 0xFF 0x00] Mode for encoding VarInts.

Currently there is no support for signed encodings. The default mode will not compile with signed values, and the legacy "nonnegative signed" mode will accept signed values, but improperly encode and decode them if they are negative. In the future, the DEFAULT mode could be extended to support negative numbers in a backwards compatible way, and additional modes could be added to support different varint formats (e.g. zigzag encoding).

◆ Using()

template<typename Formatter , typename T >
static Wrapper<Formatter, T &> Using ( T &&  t)
inlinestatic

Cause serialization/deserialization of an object to be done using a specified formatter class.

To use this, you need a class Formatter that has public functions Ser(stream, const object&) for serialization, and Unser(stream, object&) for deserialization. Serialization routines (inside READWRITE, or directly with << and >> operators), can then use Using<Formatter>(object).

This works by constructing a Wrapper<Formatter, T>-wrapped version of object, where T is const during serialization, and non-const during deserialization, which maintains const correctness.
