Configuration of the TokenReceiver. May be used for parameter validation.
RoutingMasterMode
Mode indicating whether the RoutingMaster is routing events by Sequence ID or by Send Count...
fhicl::WrappedTable< Config > Parameters
Used for ParameterSet validation (if desired)
Receives event builder "free buffer" tokens and adds them to a specified RoutingPolicy.
size_t getReceivedTokenCount() const
Returns the number of tokens that have been received.
void stopTokenReception(bool force=false)
Stops the reception of event builder tokens.
void setRunNumber(uint32_t run)
Sets the current run number.

void startTokenReception()
Starts the reception of event builder tokens.
void setStatsHelper(std::shared_ptr< StatisticsHelper > helper, std::string const &stat_key)
Specifies a StatisticsHelper instance to use when gathering statistics.
virtual ~TokenReceiver()
TokenReceiver Destructor.
void pauseTokenReception()
Temporarily suspends the reception of event builder tokens.
void resumeTokenReception()
Resumes the reception of event builder tokens after a suspension.
