Detailed Description

This class checks the validity of client request messages.

Because this class only checks the validity of messages, it can be used to check requests from clients and requests from delegates on behalf of clients.

Constructor & Destructor Documentation

ClientMessageVerifier::ClientMessageVerifier (  CODEX_Events::DeadPileType &  deadPile, CODEX_Events::QType &  eventQueue, ClientMessageHandler *  destination )

Create a ClientMessageVerifier. Parameters: deadPile  The object adds itself to this when it is ready to be garbage-collected. This is handled by the Activity base class, though the derived class must call enableTerminate() before garbage collection can occur. eventQueue  The object adds events that it emits to this so that they can be handled. destination  Another ClientMessageHandler to which an event should be sent if checking is successful.

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().

bool ClientMessageVerifier::handler (  ClientMessageEvent< SignedCreateKeyMsg > &  event  )  [virtual]

Handle a signed CreateKeyMsg. Bug: Have to cast away const for X509_verify. Implements CODEX_KeyService::ClientMessageHandler. Reimplemented in CODEX_KeyService::RoutedClientMessageVerifier. Definition at line 87 of file ClientMessageVerifier.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.
