Function documentation

TKeyXML()

 default constructor

TKeyXML(TDirectory* mother, Long64_t keyid, const TObject* obj, const char* name = 0, const char* title = 0)

 Creates TKeyXML and convert obj data to xml structures

TKeyXML(TDirectory* mother, Long64_t keyid, const void* obj, const TClass* cl, const char* name, const char* title = 0)

 Creates TKeyXML and convert obj data to xml structures

TKeyXML(TDirectory* mother, Long64_t keyid, XMLNodePointer_t keynode)

 Creates TKeyXML and takes ownership over xml node, from which object can be restored

~TKeyXML()

 TKeyXML destructor

void Delete(Option_t* option = "")

 Delete key from current directory
 Note: TKeyXML object is not deleted. You still have to call "delete key"

void StoreKeyAttributes()

 Stores keys attributes in key node

void StoreObject(const void* obj, const TClass* cl)

  convert object to xml structure and keep this structure in key

void UpdateAttributes()

 update key attributes in key node

void UpdateObject(TObject* obj)

 updates object, stored in the node
 Used for TDirectory data update

Int_t Read(TObject* tobj)

 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, from key
 if it is not TObject or in case of error, return 0

TObject* ReadObjWithBuffer(char* bufferRead)

 read object derived from TObject class, from key
 if it is not TObject or in case of error, return 0

void* ReadObjectAny(const TClass* expectedClass)

 read object of any type

void* XmlReadAny(void* obj, const TClass* expectedClass)

 read object from key and cast to expected class

TXMLEngine* XMLEngine()

 return pointer on TXMLEngine object, used for xml conversion

TKeyXML(const TKeyXML& )

TKeyXML& operator=(const TKeyXML& )

void DeleteBuffer()

{}
