Bool_t ROOT::Internal::HasConsistentHashMember ( const char *  cname)

Return true is the Hash/RecursiveRemove setup is consistent, i.e.

when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation. This routines is used for a small subset of the class for which we need the answer before gROOT is properly initialized.
