DECLARE_STREAMER macro

Streaming Macros

Syntax

DECLARE_STREAMER( exp, cls, ver )

Header File

objstrm.h

Description

This macro defines a nested class within your streamable class, and contains the core of the streaming code. DECLARE_STREAMER declares the Read and Write function declarations, whose definitions you must provide, and the Build function that calls the TStreamableClass constructor.

• The first parameter should be a macro, which in turn should conditionally expand to either __import and __export, depending on whether or not the class is to be imported or exported from a DLL.
• The second parameter is the streamable class name.
• The third parameter is the object version number.
