Function documentation


TVirtualStreamerInfo&  operator=(const TVirtualStreamerInfo& )


assignment operator





 ~TVirtualStreamerInfo()


 Destructor





Bool_t  CanDelete()


 static function returning true if ReadBuffer can delete object





Bool_t  CanOptimize()


 static function returning true if optimization can be on





TStreamerBasicType * GetElementCounter(const char* countName, TClass* cl)


 Get pointer to a TStreamerBasicType in TClass *cl
static function





Bool_t  GetStreamMemberWise()


 Return whether the TStreamerInfos will save the collections in
 "member-wise" order whenever possible.    The default is to store member-wise.
 kTRUE indicates member-wise storing
 kFALSE inddicates object-wise storing

 A collection can be saved member wise when it contain is guaranteed to be
 homogeneous.  For example std::vector<THit> can be stored member wise,
 while std::vector<THit*> can not (possible use of polymorphism).





void  Optimize(Bool_t opt = kTRUE)


  This is a static function.
  Set optimization option.
  When this option is activated (default), consecutive data members
  of the same type are merged into an array (faster).
  Optimization must be off in TTree split mode.





TVirtualStreamerInfo * Factory(TClass* cl)


 Static function returning a pointer to a new TVirtualStreamerInfo object.
 If the Info factory does not exist, it is created via the plugin manager.
 In reality the factory is an empty TStreamerInfo object.





void  SetCanDelete(Bool_t opt = kTRUE)


  This is a static function.
  Set object delete option.
  When this option is activated (default), ReadBuffer automatically
  delete objects when a data member is a pointer to an object.
  If your constructor is not presetting pointers to 0, you must
  call this static function TStreamerInfo::SetCanDelete(kFALSE);





void  SetFactory(TVirtualStreamerInfo* factory)


static function: Set the StreamerInfo factory





Bool_t  SetStreamMemberWise(Bool_t enable = kTRUE)


 Set whether the TStreamerInfos will save the collections in
 "member-wise" order whenever possible.  The default is to store member-wise.
 kTRUE indicates member-wise storing
 kFALSE inddicates object-wise storing
 This function returns the previous value of fgStreamMemberWise.





void  Streamer(TBuffer& b)


 Stream an object of class TVirtualStreamerInfo.
