kWarn |
Definition at line 39 of file TLeafObject.h.
In version of ROOT older then v6.12, kWarn was set to BIT(12) which overlaps with TBranch::kBranchObject.
Since it stored in ROOT files as part of the TBranchObject and that we want to reset in TBranchObject::Streamer, we need to keep track of the old value.
