Detailed Description

This class processes server responses to a threshold signature request for a CODEX_Client::BlindKeyMsg.

Once sufficient responses have been received, this will generate a threshold signature and return it to the client.

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().

virtual bool CODEX_Quorum::ResponseCallback::operator() (  unsigned int  server, Message *  msg )  [pure virtual, inherited]

Parameters: server  The ID of the server that sent the message being processed. msg  The message received. The callback object takes ownership of the memory.

bool SignReadCallback::operator() (  unsigned int  server, CODEX_Quorum::Message *  msg )

Bug: Have to cast away const for unmarshal. Definition at line 68 of file SignReadCallback.cc.

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.
