## Detailed Description

### template<class TYPE, class ACE_LOCK>
class ACE_DLL_Singleton_T< TYPE, ACE_LOCK >

Same as ACE_Singleton, except that it registers for destruction with the ACE_Framework_Repository instead of with the ACE_Object_Manager directly.

This version of ACE_Singleton should be used for singletons that live in a dll loaded either directly by ACE_DLL or indirectly by the ACE Service Configuration framework. Whenever ACE_DLL is ready to actually unload the dll, ACE_DLL_Singleton based dlls associated with that dll will be destroyed first. In fact, any singleton can safely use ACE_DLL_Singleton, even those that don't live in dlls. In that case, the singleton will be destroyed at normal program shutdown.

The only additional requirement is that the contained class export name() and dll_name() methods. See ACE_DLL_Singleton_Adapter_T below for a convenient example of how to satisfy this requirement for the dll_name().

Usage is the same as for ACE_Singleton, but note that if you you declare a friend, the friend class must still be an *ACE_Singleton*<T, [ACE_LOCK]>, not an ACE_Unmanaged_Singleton.
