Detailed Description
Implements behaviour from the state NotScheduled to Completed.
Once successfully scheduled to be merged by DPM (NotScheduled -> Scheduled) the "location" for the true DAQ state is also transferred. This means:
- If DPM is offline:
- OCM cannot know the true state of DAQ.
- Aborting with strict error policy cannot be done.
- Aborting with tolerant policy will forcefully abort DAQ locally but the DAQ may anyway be completed by DPM.

Constructor & Destructor Documentation
◆ DpmDaqController()
| daq::DpmDaqController::DpmDaqController | ( | boost::asio::io_context & | io_context, |
| DaqContext | context, | ||
| std::shared_ptr< ObservableStatus > | status, | ||
| std::shared_ptr< ObservableEventLog > | event_log, | ||
| std::shared_ptr< DpmClient > | dpm_client | ||
| ) |
Constructor.
@important DpmDaqController must only be used with shared_ptr.
- Parameters
-
io_context Used for async operations. context DAQ context. status DAQ status. dpm_client Interface to DPM. During construction DpmDaqController will register signal slot to receive DAQ status updates and mirror that in status accordingly.
- Exceptions
-
std::invalid_argument if state of status is not NotScheduled or subsequent.
Definition at line 733 of file daqController.cpp.
Member Function Documentation
◆ AbortAsync()
|
overridevirtual |
Attempts to abort Data Acquisition.
- If Data Acquisition is not-yet-scheduled it will be aborted immediately.
- If Data Acquisition may have been scheduled (request has been sent to DPM) the request is forwarded to DPM.
- If DPM is not running or otherwise fails the DAQ is still marked as aborted if policy is ErrorPolicy::Tolerant.
Implements daq::DaqController.
Definition at line 866 of file daqController.cpp.
◆ AwaitAsync()
|
overridevirtual |
- Returns
- future containing std::runtime_error because operation is always invalid.
Implements daq::DaqController.
Definition at line 779 of file daqController.cpp.
◆ GetState()
|
overridevirtual |
- Returns
- state of data acquisition.
Implements daq::DaqController.
Definition at line 788 of file daqController.cpp.
◆ ScheduleMergeAsync()
|
overridevirtual |
Schedules DAQ for merging by sending request to DPM.
- Returns
- future containing exception:
- std::logic_error if DAQ has already been scheduled
- mal::TimeoutException if DPM is offline (timeout).
- unspecified DPM fails
Implements daq::DaqController.
Definition at line 792 of file daqController.cpp.
◆ StartAsync()
|
overridevirtual |
- Returns
- future containing std::runtime_error because operation is always invalid.
Implements daq::DaqController.
Definition at line 768 of file daqController.cpp.
◆ StopAsync()
|
overridevirtual |
- Returns
- future containing std::runtime_error because operation is always invalid.
Implements daq::DaqController.
Definition at line 773 of file daqController.cpp.
◆ UpdateKeywords()
|
overridevirtual |
- Exceptions
-
std::runtime_error because operation is always invalid (keywords cannot be modified once delivered to DPM).
Implements daq::DaqController.
