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).

◆ 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.
