boost::openmethod::registry::registry_type

Declared in <boost/openmethod/preamble.hpp>

registry_type is the registry specialization itself ‐ for a registry defined as a struct deriving from registry (like default_registry), the base class, not the struct. It is the type on which the registry's state is keyed. Two structs that derive from the same specialization therefore share one state, and are one registry; see registry for how to keep two of them apart. It also appears in the explicit instantiation / extern template declaration pair that shares a custom registry's state across shared libraries: registry_state<my_registry::registry_type> (see registry_state).
