This class is described in an article in the July/August 1994 issue of the C++ Report magazine. It implements a templatized version of the Decorator pattern from the GoF book.
ACE_Atomic_Op_Ex objects must be constructed with a reference to an existing lock. A single lock can be shared between multiple ACE_Atomic_Op_Ex objects. If you do not require this ability consider using the ACE_Atomic_Op class instead, which may be able to take advantage of platform-specific optimisations to provide atomic operations without requiring a lock.

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_LOCK & ACE_Atomic_Op_Ex< ACE_LOCK, TYPE >::mutex | ( | void | ) | [inline] |
Returns a reference to the underlying <ACE_LOCK>. This makes it possible to acquire the lock explicitly, which can be useful in some cases if you instantiate the <ACE_Atomic_Op_Ex> with an ACE_Recursive_Mutex or ACE_Process_Mutex.
ACE_INLINE TYPE & ACE_Atomic_Op_Ex< ACE_LOCK, TYPE >::value_i | ( | void | ) | [inline] |
Explicitly return value_
(by reference). This gives the user full, unrestricted access to the underlying value. This method will usually be used in conjunction with explicit access to the lock. Use with care ;-)
ACE_LOCK& ACE_Atomic_Op_Ex< ACE_LOCK, TYPE >::mutex_ [private] |
Type of synchronization mechanism.
TYPE ACE_Atomic_Op_Ex< ACE_LOCK, TYPE >::value_ [private] |
Current object decorated by the atomic op.
