◆ GetStreamMemberWise()

Bool_t TVirtualStreamerInfo::GetStreamMemberWise ( )

static

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).
