It makes use of the AR and TAR classes to give the necessary external interface. There are only two things that can be done with a raw package, extract it's control information and extract the contents itself. This should probably subclass an as-yet unwritten super class to produce a generic archive mechanism. The memory control file extractor is useful to extract a single file into memory from the control.tar.gz ##################################################################### */ /*}}}*/ #ifndef PKGLIB_DEBFILE_H #define PKGLIB_DEBFILE_H #include <apt-pkg/arfile.h> #include <apt-pkg/dirstream.h> #include <apt-pkg/tagfile.h> #include <apt-pkg/pkgcache.h> class FileFd; class pkgDataBase; class debDebFile { protected: FileFd &File; ARArchive AR; bool CheckMember(const char *Name); public: class ControlExtract; class MemControlExtract; bool ExtractControl(pkgDataBase &DB); bool ExtractArchive(pkgDirStream &Stream); pkgCache::VerIterator MergeControl(pkgDataBase &DB); const ARArchive::Member *GotoMember(const char *Name); inline FileFd &GetFile() {return File;}; debDebFile(FileFd &File); }; class debDebFile::ControlExtract : public pkgDirStream { public: virtual bool DoItem(Item &Itm,int &Fd); }; class debDebFile::MemControlExtract : public pkgDirStream { bool IsControl; public: char *Control; pkgTagSection Section; unsigned long Length; std::string Member; // Members from DirStream virtual bool DoItem(Item &Itm,int &Fd); virtual bool Process(Item &Itm,const unsigned char *Data, unsigned long Size,unsigned long Pos); // Helpers bool Read(debDebFile &Deb); bool TakeControl(const void *Data,unsigned long Size); MemControlExtract() : IsControl(false), Control(0), Length(0), Member("control") {}; MemControlExtract(std::string Member) : IsControl(false), Control(0), Length(0), Member(Member) {}; ~MemControlExtract() {delete [] Control;}; }; /*}}}*/ #endif
