vrpn_bool | isSerializer (void) const |
void | useLamportClock (vrpn_LamportClock *) |
Lamport Clocks are NOT currently integrated. They should provide serialization (virtual timestamps) that work even when the clocks of the computers communicating are not roughly synchronized. | |
void | becomeSerializer (void) |
Requests that this instance of the shared object becomes the serializer (i.e. lock-arbitrator), and we can then use setSerializerPolicy to imitate a complete lock. Does nothing if we already are the serializer (isSerializer() returns true); otherwise initiates a 3-phase request protocol with the current serializer. There currently isn't any provision for notification of success (or failure). | |
vrpn_bool | registerDeferredUpdateCallback (vrpnDeferredUpdateCallback, void *userdata) |
The specified function will be passed userdata when this particular shared object defers an update (receives a local update but is not the serializer and so sends the update off to the serializer). Intended to allow insertion of timing code for those times when you really want to know how long every little thing is taking. | |

As long as we have inorder delivery, this should be sufficient to keep us from getting many at once. | |
vrpn_bool | d_queueSets |
If this is true, no set()s are processed; instead, they are queued for later execution. NOT IMPLEMENTED. | |
