This group includes macro definitions used to define operations that enable objects to be serialized.
While not directly part of object streams, these macros make heavy use of the object streams interface, delegating most of the work of object serialization back to the object stream implementation. Object streams are thus able to control nearly all aspects of object serialization, not just the format of primitive data types like virtual streams.
Some of these macros have positional restrictions with respect to each other. As a general rule of thumb, the RW_XXX_AS_SELF macros come before RW_XXX_AS_BASE macros. For more insight, please see Section 6.4, "Basic Examples," in the Advanced Tools Module User's Guide.
| #define RW_BEGIN_EXTERNAL_STREAM_CONTENTS | ( | Class | ) |
Starts the streamContents() function. Put in separate source file. For external serialization only. (For intrusive, use RW_BEGIN_STREAM_CONTENTS.)
| #define RW_BEGIN_STREAM_CONTENTS | ( | Class | ) |

| #define RW_DECLARE_EXTERNAL_STREAMABLE_AS_BASE | ( | Class, | |
| Other ) |
Allows concrete derived types to be streamed out and streamed back in as pointers to their base class. Place RW_DECLARE_EXTERNAL_STREAMABLE_AS_BASE in your header, after the declaration of the class.
