Detailed Description

Provide the abstract base class common to all service implementations.

Classes that inherit from ACE_Service_Objects are capable of being registered with the ACE_Reactor (due to the ACE_Event_Handler, as well as being dynamically linked by the ACE_Service_Config (due to the ACE_Shared_Object).
