Detailed Description

template<class I>
class mi::base::Interface_implement_singleton<I>

Mixin class template for deriving singleton interface implementations, where the reference count is fixed to one.

mi::base::Interface_implement is a mixin class template that allows you to derive interface class implementations easily. It provides you with a special implementation of reference counting and the mi::base::IInterface::get_interface(const Uuid&) method. It requires that you used interfaces derived from the corresponding mixin class template mi::base::Interface_declare.

The reference counting is fixed to have a count of always one. It is suitable, for example, for singleton objects that get once allocated and never deallocated.

mi::base::Interface_implement is derived from the interface I.

Template Parameters
IThe interface class that this class implements.
