ROOT::Internal::TDirectoryAtomicAdapter Struct Reference

Internal class used in the implementation of gDirectory The objects of type TDirectoryAtomicAdapter should only be used inside the thread that created them.

The intent is for those objects to be used indirectly through the macro gDirectory and solely as temporary objects. For example:

gDirectory = newvalue;
gDirectory->ls();
TDirectory *current = gDirectory;

Note that:

auto dir = gDirectory;

currently behaves "unexpectedly" as changing dir will also change gDirectory:

dir = newvalue;

leads to

gDirectory == newvalue

To prevent this we would need a new mechanism such that the type used by auto in that case is TDirectory* rather than the Internal type TDirectoryAtomicAdapter.
