Member Function Documentation

void Activity::enableTerminate (   )  [protected, inherited]

This method should be called when an Activity has received a CloseEvent or other indicator that it is no longer needed. Actual termination will not occur until there are no remaining events outstanding (unacknowledged). Definition at line 63 of file Activity.cc. Referenced by CODEX_KeyService::ClientActivity::handler(), and CODEX_KeyService::ClientActivity::processRequest().

bool Activity::handler (  EventAck &  event  )  [virtual, inherited]

The base class is responsible for handling acknowledgements, which are relevant to whether the Activity is ready for deletion. If a derived class reimpliments this method, it must call this version explicitly. Definition at line 39 of file Activity.cc. Referenced by CODEX_Events::EventAck::handle(), and CODEX_KeyService::ClientActivity::handler().

void MessageParser::operator() (  unsigned char *  server, unsigned char *  mID, CODEX_Quorum::Message *  m )  [virtual]

Parse and dispatch a message. The memory for all arguments is taken over by the MessageParser. Parameters: server  Originating server mID  Unique ID for the message m  Marshalled message Implements CODEX_Server::MessageParser. Definition at line 27 of file MessageParser.cc. References CODEX_Events::Activity::sendEvent(), CODEX_APSS::SignatureMask, and CODEX_APSS::RoutedMessageEventBase::unmarshal().

void Activity::sendEvent (  EventBase *  event, Activity *  source, bool  failure = false )  [protected, inherited]

Parameters: event  New event to be added to the queue source  Source of event just handled, to which an acknowledgement should be sent. This is accessed by the method EventBase::source(). failure  Is the acknowledgment a negative ack? Definition at line 49 of file Activity.cc. References CODEX_Events::Activity::m_queue.
