The 'Meta' information for a package is the control information and setup scripts stored inside the archive. GetMetaTmp returns the name of a directory that is used to store named files containing the control information. The File Listing is the database of installed files. It is loaded into the memory/persistent cache structure by the ReadFileList method. ##################################################################### */ /*}}}*/ #ifndef PKGLIB_DATABASE_H #define PKGLIB_DATABASE_H #include <apt-pkg/pkgcachegen.h> #include <string> class pkgFLCache; class OpProgress; class pkgDataBase { protected: pkgCacheGenerator *Cache; pkgFLCache *FList; std::string MetaDir; virtual bool InitMetaTmp(std::string &Dir) = 0; public: // Some manipulators for the cache and generator inline pkgCache &GetCache() {return Cache->GetCache();}; inline pkgFLCache &GetFLCache() {return *FList;}; inline pkgCacheGenerator &GetGenerator() {return *Cache;}; bool GetMetaTmp(std::string &Dir); virtual bool ReadyFileList(OpProgress &Progress) = 0; virtual bool ReadyPkgCache(OpProgress &Progress) = 0; virtual bool LoadChanges() = 0; pkgDataBase() : Cache(0), FList(0) {}; virtual ~pkgDataBase(); }; #endif
