Detailed Description

template<typename TAG>
class Stroika::Foundation::Common::UniqueID< TAG >

An opaque ID - each New () one never given before, in this process - of a type of its own for each TAG, so one kind cannot be passed for another. UniqueID{} names nothing.

For naming what was added - a callback, a timer, a task - so it can be removed, or asked about, later, without comparing the things themselves (

See also

Execution::CallbackRegistry for why). One made up (UniqueID{}, or another's) names nothing added, so New () need not be guarded.

Example Usage

class Thing {
public:
    using ID = Common::UniqueID<Thing>;
    ID   Add (...);         // ID id = ID::New (); ...; return id;
    void Remove (ID id);
};
