Apr, 2018 This is like SG::ConstAccessor, except that accesses to the underlying T variable are cast to std::atomic<T>. This will generally work only for fundamental integer types or for pointers.

This is the way to access variables that were declared with Flags::Atomic . Be aware, however, that it is still possible to have non-atomic accesses to such variables via either the implicit operations provided by AuxTypeRegistry or by explicit access to the value vector. Therefore, this is not recommended for general use. Contact core software before using this for new code.
