Also it allows for default // error reporting for ANY types that have not been // instantiated properly. // // Copyright (C) 1992 Michael Sample and the University of British Columbia // // This library is free software; you can redistribute it and/or // modify it provided that this copyright/license information is retained // in original form. // // If you modify this file, you must clearly indicate your changes. // // This source code is distributed in the hope that it will be // useful, but WITHOUT ANY WARRANTY; without even the implied warranty // of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. // // MS 92 // // $Header: /cvs/Darwin/Security/SecuritySNACCRuntime/c++-lib/inc/asn-type.h,v 1.1.1.1 2001/05/18 23:14:06 mb Exp $ // $Log: asn-type.h,v $ // Revision 1.1.1.1 2001/05/18 23:14:06 mb // Move from private repository to open source repository // // Revision 1.3 2001/05/05 00:59:18 rmurphy // Adding darwin license headers // // Revision 1.2 2000/06/15 18:48:24 dmitch // Snacc-generated source files, now part of CVS tree to allow for cross-platform build of snaccRuntime. // // Revision 1.1.1.1 2000/03/09 01:00:05 rmurphy // Base Fortissimo Tree // // Revision 1.2 1999/03/21 02:07:33 mb // Added Copy to every AsnType. // // Revision 1.1 1999/02/25 05:21:46 mb // Added snacc c++ library // // Revision 1.6 1997/02/16 20:25:48 rj // check-in of a few cosmetic changes // // Revision 1.5 1995/07/24 17:39:00 rj // _getref() gets an additional optional argument to faciliate the different member access semantics of TclGetVal() and TclSetVal(). // // _typename() made private, no need to be public. // // additional function TclUnsetVal() to delete OPTIONAL members and SEQUENCE OF and SET OF list elements. // // #if TCL ... #endif wrapped into #if META ... #endif // // getTclPDU() deleted. // // changed `_' to `-' in file names. // // Revision 1.4 1994/10/08 04:18:10 rj // code for meta structures added (provides information about the generated code itself). // // code for Tcl interface added (makes use of the above mentioned meta code). // // virtual inline functions (the destructor, the Clone() function, BEnc(), BDec() and Print()) moved from inc/*.h to src/*.C because g++ turns every one of them into a static non-inline function in every file where the .h file gets included. // // made Print() const (and some other, mainly comparison functions). // // several `unsigned long int' turned into `size_t'. // // Revision 1.3 1994/09/13 14:18:52 rj // inline functions moved from asn_type.h to asn_type.C. // functions that are called upon error only don't need to be that fast. // // Revision 1.2 1994/08/28 10:00:57 rj // comment leader fixed. // // Revision 1.1 1994/08/28 09:20:44 rj // first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog. #ifndef _asn_type_h_ #define _asn_type_h_ #ifdef _IBM_ENC_ #include "shmmgr.h" // Guido Grassel 4.8.93 #endif /* _IBM_ENC_ */ #define SUPPORT_ANY_TYPE #if TCL #include <Tcl/tcl.h> #undef VOID #endif #if META #include "meta.h" #endif #ifndef __IBM_ENC_ class AsnType #else class AsnType: public MemMgr // Guido Grassel, 12.8.93 #endif /* __IBM_ENC_ */ { public: virtual ~AsnType(); #ifdef SUPPORT_ANY_TYPE virtual AsnType *Clone() const; virtual AsnType *Copy() const; virtual void BDec (BUF_TYPE b, AsnLen &bytesDecoded, ENV_TYPE env); virtual AsnLen BEnc (BUF_TYPE b); #else void BDec (BUF_TYPE b, AsnLen &bytesDecoded, ENV_TYPE env) {} AsnLen BEnc (BUF_TYPE b) { return 0; } #endif virtual void Print (ostream &) const; #if META static const AsnTypeDesc _desc; virtual const AsnTypeDesc *_getdesc() const; virtual AsnType *_getref (const char *membername, bool create=false); private: const char *_typename() const; #if TCL public: virtual int TclGetDesc (Tcl_DString *) const; virtual int TclGetVal (Tcl_Interp *) const; virtual int TclSetVal (Tcl_Interp *, const char *val); virtual int TclUnsetVal (Tcl_Interp *, const char *membernames); #endif // TCL #endif // META }; #endif // conditional include
