* COPYENGN.H
|
|
*
|
|
* Header file for ArchiveLib 2.0
|
|
*
|
|
* Copyright (c) 1994, 1995 Greenleaf Software, Inc.
|
|
* All Rights Reserved
|
|
*
|
|
* DESCRIPTION
|
|
*
|
|
* This header file contains the class definition for the derived
|
|
* classes ALCopyCompressor and ALCopyDecompressor.
|
|
*
|
|
* CLASS DEFINITIONS:
|
|
*
|
|
* ALCopyCompressor
|
|
* ALCopyDecompressor
|
|
*
|
|
* REVISION HISTORY
|
|
*
|
|
* May 26, 1994 1.0A : First release
|
|
*
|
|
* July 8, 1994 1.0B : In most of my class definitions I create a prototype
|
|
* for a private/protected copy constructor and
|
|
* assignment operator, because I don't want the compiler
|
|
* to create default versions. I forgot to do it for
|
|
* this class, which didn't cause any trouble under
|
|
* MS-DOS. gcc under UNIX flagged the problem, which
|
|
* I fixed by adding the prototypes.
|
|
*
|
|
* January 1, 1995 1.01A : Changed include of storage.h to stor.h. Had
|
|
* clash with the new header file
|
|
* STORAGE.H used by compiler vendors for
|
|
* OLE implementation.
|
|
*
|
|
* February 14, 1996 2.0: New release
