Detailed Description

Activator that is registered with the POA for facet and consumer servants.

This class acts like a factory in some sense. This factory is registered with the POA with RETAIN policy. When the factory gets a call back as part of the upcall, this factory looks at the list of port activators registered, uses the OID to pick the right one (yes a linear algorithm is used), calls activate () on it which returns the servant for *that* port.

typedef ACE_Array_Base<Port_Activator *> CIAO::Servant_Activator::Port_Activators [private]

@ This should be changed at some point of time so that we don't land up with a linear algorithm
