The versioning system represents how versions are compared, represented and how dependencies are evaluated. As a general rule versioning systems are not compatible unless specifically allowed by the TestCompatibility query. The versions are stored in a global list of versions, but that is just so that they can be queried when someone does 'apt-get -v'. pkgSystem provides the proper means to access the VS for the active system. ##################################################################### */ /*}}}*/ #ifndef PKGLIB_VERSION_H #define PKGLIB_VERSION_H #ifdef __GNUG__ #pragma interface "apt-pkg/version.h" #endif #include <string> class pkgVersioningSystem { public: // Global list of VS's static pkgVersioningSystem **GlobalList; static unsigned long GlobalListLen; static pkgVersioningSystem *GetVS(const char *Label); const char *Label; // Compare versions.. virtual int DoCmpVersion(const char *A,const char *Aend, const char *B,const char *Bend) = 0; virtual bool CheckDep(const char *PkgVer,int Op,const char *DepVer) = 0; virtual int DoCmpReleaseVer(const char *A,const char *Aend, const char *B,const char *Bend) = 0; virtual string UpstreamVersion(const char *A) = 0; // See if the given VS is compatible with this one.. virtual bool TestCompatibility(pkgVersioningSystem const &Against) {return this == &Against;}; // Shortcuts inline int CmpVersion(const char *A, const char *B) { return DoCmpVersion(A,A+strlen(A),B,B+strlen(B)); }; inline int CmpVersion(string A,string B) { return DoCmpVersion(A.begin(),A.end(),B.begin(),B.end()); }; inline int CmpReleaseVer(const char *A, const char *B) { return DoCmpReleaseVer(A,A+strlen(A),B,B+strlen(B)); }; inline int CmpReleaseVer(string A,string B) { return DoCmpReleaseVer(A.begin(),A.end(),B.begin(),B.end()); }; pkgVersioningSystem(); virtual ~pkgVersioningSystem() {}; }; #ifdef APT_COMPATIBILITY #include <apt-pkg/debversion.h> #endif #endif
