class TKeySQL: public TKey


 TKeySQL is represents a metainforamtion about object, which was written to
 SQL database. It keeps object id, which used to locate object data
 from database tables.

Function documentation

TKeySQL()
 default constructor
TKeySQL(TDirectory* mother, const TObject* obj, const char* name, const char* title = 0)
 Creates TKeySQL and convert obj data to TSQLStructure via TBufferSQL2
TKeySQL(TDirectory* mother, const void* obj, const TClass* cl, const char* name, const char* title = 0)
 Creates TKeySQL and convert obj data to TSQLStructure via TBufferSQL2
TKeySQL(TDirectory* mother, Long64_t keyid, Long64_t objid, const char* name, const char* title, const char* keydatetime, Int_t cycle, const char* classname)
 Create TKeySQL object, which correponds to single entry in keys table
~TKeySQL()
 TKeySQL destructor
Bool_t IsKeyModified(const char* keyname, const char* keytitle, const char* keydatime, Int_t cycle, const char* classname)
 Compares keydata with provided and return kTRUE if key was modified
 Used in TFile::StreamKeysForDirectory() method to verify data for that keys
 should be updated
void Delete(Option_t* option = "")
 Removes key from current directory
 Note: TKeySQL object is not deleted. You still have to call "delete key"
Long64_t GetDBDirId() const
 return sql id of parent directory
void StoreKeyObject(const void* obj, const TClass* cl)
 Stores object, associated with key, into data tables
Int_t Read(TObject* obj)
 To read an object from the file.
 The object associated to this key is read from the file into memory.
 Before invoking this function, obj has been created via the
 default constructor.
TObject* ReadObj()
 Read object derived from TObject class
 If it is not TObject or in case of error, return 0
TObject* ReadObjWithBuffer(char* bufferRead)
 Read object derived from TObject class
 If it is not TObject or in case of error, return 0
void* ReadObjectAny(const TClass* expectedClass)
 read object of any type from SQL database
void* ReadKeyObject(void* obj, const TClass* expectedClass)
 Read object, associated with key, from database
TKeySQL(const TKeySQL& )
TKeySQL& operator=(const TKeySQL& )
Int_t Read(const char* name)
{ return TKey::Read(name); }
Long64_t GetDBKeyId() const

Long64_t GetDBObjId() const
{ return fObjId; }
void DeleteBuffer()
{}
void FillBuffer(char*& )
{}
char * GetBuffer() const
{ return 0; }
Long64_t GetSeekKey() const
{ return GetDBObjId() > 0 ? GetDBObjId() : 0; }
Long64_t GetSeekPdir() const
{ return GetDBDirId() > 0 ? GetDBDirId() : 0; }
void Keep()
