Return whether the TStreamerInfos will save the collections in "member-wise" order whenever possible.

The default is to store member-wise.

  • 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).

◆ NewInfo()

virtual TVirtualStreamerInfo* TVirtualStreamerInfo::NewInfo ( TClass cl)
pure virtual

Implemented in TStreamerInfo.

◆ operator=()

TVirtualStreamerInfo & TVirtualStreamerInfo::operator= ( const TVirtualStreamerInfo info)

◆ Optimize()

void TVirtualStreamerInfo::Optimize ( Bool_t  opt = kTRUE)
static

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.

◆ SetCanDelete()

void TVirtualStreamerInfo::SetCanDelete ( Bool_t  opt = kTRUE)
static

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);

◆ SetStreamMemberWise()

Bool_t TVirtualStreamerInfo::SetStreamMemberWise ( Bool_t  enable = kTRUE)
static

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 indicates object-wise storing This function returns the previous value of fgStreamMemberWise.
