Detailed Description
template<class ACE_LOCK, typename TYPE>
class ACE_Atomic_Op< ACE_LOCK, TYPE >
Transparently parameterizes synchronization into basic arithmetic operations.
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.
Certain platforms may provide a template specialization for ACE_Atomic_Op <ACE_Thread_Mutex, long> that provides optimized atomic integer operations without actually requiring a mutex.

| ACE_INLINE TYPE ACE_Atomic_Op< ACE_LOCK, TYPE >::value | ( | void | ) | const [inline] |
Explicitly return value_.
| ACE_INLINE void ACE_Atomic_Op< ACE_LOCK, TYPE >::dump | ( | void | ) | const [inline] |
Dump the state of an object.
| ACE_INLINE ACE_LOCK & ACE_Atomic_Op< 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 with an ACE_Recursive_Mutex or ACE_Process_Mutex.
- Deprecated:
- This member function is deprecated and so may go away in the future. If you need access to the underlying mutex, consider using the ACE_Atomic_Op_Ex template instead.
| ACE_INLINE TYPE & ACE_Atomic_Op< 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 ;-)
