◆ 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.
