Macros for External Serialization
Some of the macros mentioned earlier can be used for either intrusive or external serialization. Others, such as RW_DECLARE_VIRTUAL_STREAM_FNS, for example, can be used only in the class files. In those cases, the Serialization package provides equivalent external macros:
RW_DECLARE_EXTERNAL_STREAM_FNSRW_DECLARE_EXTERNAL_STREAMABLE_POINTERRW_DEFINE_EXTERNAL_STREAMABLE_POINTERRW_DECLARE_EXTERNAL_STREAMABLE_AS_SELFRW_DEFINE_EXTERNAL_STREAMABLE_AS_SELFRW_DECLARE_EXTERNAL_STREAMABLE_AS_BASERW_DEFINE_EXTERNAL_STREAMABLE_AS_BASERW_BEGIN_EXTERNAL_STREAM_CONTENTSRW_STREAM_EXTERNAL_PARENT
