In the final scheme of things this may serve as a director class to access the actual install methods based on the file type being installed. ##################################################################### */ /*}}}*/ // Header section: pkglib #ifndef PKGLIB_PACKAGEMANAGER_H #define PKGLIB_PACKAGEMANAGER_H #ifdef __GNUG__ #pragma interface "apt-pkg/packagemanager.h" #endif #include <string> #include <apt-pkg/pkgcache.h> class pkgAcquire; class pkgDepCache; class pkgSourceList; class pkgOrderList; class pkgRecords; class pkgPackageManager { public: enum OrderResult {Completed,Failed,Incomplete}; protected: string *FileNames; pkgDepCache &Cache; pkgOrderList *List; bool Debug; // Bring some usefull types into the local scope typedef pkgCache::PkgIterator PkgIterator; typedef pkgCache::VerIterator VerIterator; typedef pkgCache::DepIterator DepIterator; typedef pkgCache::PrvIterator PrvIterator; typedef pkgCache::Version Version; typedef pkgCache::Package Package; bool DepAdd(pkgOrderList &Order,PkgIterator P,int Depth = 0); OrderResult OrderInstall(); bool CheckRConflicts(PkgIterator Pkg,DepIterator Dep,const char *Ver); bool CreateOrderList(); // Analysis helpers bool DepAlwaysTrue(DepIterator D); // Install helpers bool ConfigureAll(); bool SmartConfigure(PkgIterator Pkg); bool SmartUnPack(PkgIterator Pkg); bool SmartRemove(PkgIterator Pkg); bool EarlyRemove(PkgIterator Pkg); // The Actuall installation implementation virtual bool Install(PkgIterator /*Pkg*/,string /*File*/) {return false;}; virtual bool Configure(PkgIterator /*Pkg*/) {return false;}; virtual bool Remove(PkgIterator /*Pkg*/,bool /*Purge*/=false) {return false;}; virtual bool Go() {return true;}; virtual void Reset() {}; public: // Main action members bool GetArchives(pkgAcquire *Owner,pkgSourceList *Sources, pkgRecords *Recs); OrderResult DoInstall(); bool FixMissing(); pkgPackageManager(pkgDepCache &Cache); virtual ~pkgPackageManager(); }; #endif
