- All Implemented Interfaces:
 
- Ice.TwowayCallback, Ice.TwowayCallbackLong, Ice.TwowayCallbackLongUE
 
public abstract class Callback_ServiceFactory_keepAllAlive
extends IceInternal.TwowayCallback
implements Ice.TwowayCallbackLongUE
Requests that the given services be marked as alive. It is
 possible that one of the services has already timed out, in which
 case the returned long value will be non-zero.
 
 Specifically, the bit representing the 0-based index will be 1:
 if (retval & 1<<idx == 1<<idx) { // not alive }
 
 Except for fatal server or session errors, this method should never
 throw an exception.
