A data processor translates an object into a format that can be stored or vice versa.
A data processor can be either in saving or loading mode.
std::enable_if< std::is_enum<T>::value && !detail::has_serialize<T>::value, error >::type caf::data_processor< Derived >::apply | ( | T & | x | ) |
Serializes enums using the underlying type if no user-defined serialization is defined.
|
pure virtual |
Begins processing of an object.
Saves the type information to the underlying storage when in saving mode, otherwise extracts them and sets both arguments accordingly.
Implemented in caf::stream_deserializer< Streambuf >, and caf::stream_serializer< Streambuf >.
|
pure virtual |
Begins processing of a sequence.
Saves the size to the underlying storage when in saving mode, otherwise sets num
accordingly.
Implemented in caf::stream_deserializer< Streambuf >, and caf::stream_serializer< Streambuf >.
