ConfigureHelper Class

Detailed Description

ConfigureHelper tracks whether an object has been properly configured and activated, with optional logging of state changes and warnings. It enforces proper lifecycle ordering: construction, configuration, activation, deactivation, destruction.

The state is safe to read from any thread. The flags are atomic, and a mutex guards the failure reason. An AsyncStore worker reads the helper of a SimpleDataStore subclass when it loads or saves, while the owner configures and activates it on its own thread. The owner must still do each configure() and activate() on one thread.
