Detailed Description

template<class T>
class Loki::LockedStorage< T >

Implementation of the StoragePolicy used by SmartPtr.

Each call to operator-> locks the object for the duration of a call to a member function of T.

How It Works

LockedStorage has a helper class called Locker, which acts as a smart pointer with limited abilities. LockedStorage::operator-> returns an unnamed temporary of type Locker<T> that exists for the duration of the call to a member function of T. The unnamed temporary locks the object when it is constructed by operator-> and unlocks the object when it is destructed.

Note:

This storage policy requires class T to have member functions Lock and Unlock. If your class does not have Lock or Unlock functions, you may either make a child class which does, or make a policy class similar to LockedStorage which calls other functions to lock the object.
