Detailed Description

template<class TYPE, class ACE_LOCK>
class ACE_TSS_Singleton< TYPE, ACE_LOCK >

This class uses the Adapter pattern to turn ordinary classes into Thread-specific Singletons optimized with the Double-Checked Locking optimization pattern.

This implementation is another variation on the GoF Singleton pattern. In this case, a single <ACE_TSS_Singleton<TYPE, LOCK> > instance is allocated here, not a <TYPE> instance. Each call to the <instance> static method returns a Singleton whose pointer resides in thread-specific storage. As with ACE_Singleton, we use the ACE_Object_Manager so that the Singleton can be cleaned up when the process exits. For this scheme to work, a (static) cleanup() function must be provided. ACE_Singleton provides one so that TYPE doesn't need to.
