Detailed Description

Keep a table with all the ORBs in the system.

CORBA::ORB_init() is supposed to return the same ORB if the user specifies the same ORBid, either in the ORB_init() parameter or in the -ORBid option. This class is used to implement that feature. It is also useful when trying to determine if an object reference is collocated or not.

Note:
This class should be instantiated via its instance() method. Normally this would be enforced by making the constructor protected but that forces a friend declaration containing a template type (TAO_Singleton) with a static member to be introduced. In turn, this potentially introduces problems in MS Windows DLL environments due to the occurance of multiple singleton instances. There should only be one!
