Join any data-taking threads. Should be called when destructing CommandableFragmentGenerator. More... | |
bool | getNext (FragmentPtrs &output) overridefinal |
getNext calls either applyRequests or getNext_ to get any data that is ready to be sent to the EventBuilders More... | |
void | applyRequestsIgnoredMode (artdaq::FragmentPtrs &frags) |
Create fragments using data buffer for request mode Ignored. Precondition: dataBufferMutex_ and request_mutex_ are locked More... | |
void | applyRequestsSingleMode (artdaq::FragmentPtrs &frags) |
Create fragments using data buffer for request mode Single. Precondition: dataBufferMutex_ and request_mutex_ are locked More... | |

void | applyRequestsWindowMode (artdaq::FragmentPtrs &frags) |
Create fragments using data buffer for request mode Window. Precondition: dataBufferMutex_ and request_mutex_ are locked More... | |
bool | applyRequests (FragmentPtrs &frags) |
See if any requests have been received, and add the corresponding data Fragment objects to the output list. More... | |
bool | sendEmptyFragment (FragmentPtrs &frags, size_t sequenceId, std::string desc) |
Send an EmptyFragmentType Fragment. More... | |
void | sendEmptyFragments (FragmentPtrs &frags, std::map< Fragment::sequence_id_t, Fragment::timestamp_t > &requests) |
This function is for Buffered and Single request modes, as they can only respond to one data request at a time If the request message seqID > ev_counter, simply send empties until they're equal. More... | |
void | checkOutOfOrderWindows (Fragment::sequence_id_t seq) |
Check the windows_sent_ooo_ map for sequence IDs that may be removed. More... | |
std::map < Fragment::sequence_id_t, std::chrono::steady_clock::time_point > | getOutOfOrderWindowList () const |
Access the windows_sent_ooo_ map. More... | |
void | startDataThread () |
Function that launches the data thread (getDataLoop()) | |
void | startMonitoringThread () |
Function that launches the monitoring thread (getMonitoringDataLoop()) | |
void | getDataLoop () |
When separate_data_thread is set to true, this loop repeatedly calls getNext_ and adds returned Fragment objects to the data buffer, blocking when the data buffer is full. | |
bool | waitForDataBufferReady () |
Wait for the data buffer to drain (dataBufferIsTooLarge returns false), periodically reporting status. More... | |
bool | dataBufferIsTooLarge () |
Test the configured constraints on the data buffer. More... | |
void | getDataBufferStats () |
Calculate the size of the dataBuffer and report appropriate metrics. More... | |
void | checkDataBuffer () |
Perform data buffer pruning operations. If the RequestMode is Single, removes all but the latest Fragment from the data buffer. In Window and Buffer RequestModes, this function discards the oldest Fragment objects until the data buffer is below its size constraints, then also checks for stale Fragments, based on the timestamp of the most recent Fragment. | |
void | getMonitoringDataLoop () |
This function regularly calls checkHWStatus_(), and sets the isHardwareOK flag accordingly. | |
std::vector < Fragment::fragment_id_t > | fragmentIDs () override |
Get the list of Fragment IDs handled by this CommandableFragmentGenerator. More... | |
size_t | ev_counter () const |
Get the current value of the event counter. More... | |

Stop the CommandableFragmentGenerator. More... | |
void | PauseCmd (uint64_t timeout, uint64_t timestamp) |
Pause the CommandableFragmentGenerator. More... | |
void | ResumeCmd (uint64_t timeout, uint64_t timestamp) |
Resume the CommandableFragmentGenerator. More... | |
std::string | ReportCmd (std::string const &which="") |
Get a report about a user-specified run-time quantity. More... | |

Get the name used when reporting metrics. More... | |

The meta-command is used for implementing user-specific commands in a CommandableFragmentGenerator. More... | |
Protected Member Functions | |
bool | getNext_ (artdaq::FragmentPtrs &frags) override |

int | board_id () const |
Gets the current board_id. More... | |
int | fragment_id () const |
Get the current Fragment ID, if there is only one. More... | |
size_t | ev_counter_inc (size_t step=1, bool force=false) |
Increment the event counter, if the current RequestMode allows it. More... | |
void | set_exception (bool exception) |
Control the exception flag. More... | |
void | metricsReportingInstanceName (std::string const &name) |
Sets the name for metrics reporting. More... | |
std::string | printMode_ () |
Return the string representation of the current RequestMode. More... | |
virtual bool | getNext_ (FragmentPtrs &output)=0 |
Obtain the next group of Fragments, if any are available. Return false if readout cannot continue, if we are 'stopped', or if we are not running in state-machine mode. Note that getNext_() must return n of each fragmentID declared by fragmentIDs_(). More... | |
virtual void | pauseNoMutex () |
On call to PauseCmd, pauseNoMutex() is called prior to PauseCmd acquiring the mutex More... | |
virtual std::string | report () |
Let's say that the contract with the report() functions is that they return a non-empty string if they have something useful to report, but if they don't know how to handle a given request, they simply return an empty string and the ReportCmd() takes care of saying "the xyz command is not currently supported". For backward compatibility, we keep the report function that takes no arguments and add one that takes a "which" argument. In the ReportCmd function, we'll call the more specific one first. More... | |
virtual std::string | reportSpecific (std::string const &what) |
Report the status of a specific quantity More... | |
