Detailed Description

template<class SVC_HANDLER>
class ACE_Singleton_Strategy< SVC_HANDLER >

Defines the interface for specifying a creation strategy for a that always returns the same (i.e., it's a Singleton).

Note that this class takes over the ownership of the SVC_HANDLER passed into it as a parameter and it becomes responsible for deleting this object.
