Member Function Documentation

AbortAsync()

auto daq::DpmClientImpl::AbortAsync ( std::string const &  id ) -> boost::future<State>

overridevirtual

Abort merging.

Implements daq::DpmClient.

Definition at line 105 of file dpmClient.cpp.

ConnectStatusSignal()

auto daq::DpmClientImpl::ConnectStatusSignal ( StatusSignal::slot_type const &  slot ) -> boost::signals2::connection

overridevirtual

Connect slot to status change signal.

DpmClient ensures that signals are only emitted from main thread.

Note

Status may come from different sources and no total order is guaranteed. Observers of status changes should make effort to discard/ignore changes that occurred before already recorded status updated.

Implements daq::DpmClient.

Definition at line 197 of file dpmClient.cpp.

ConnectStorageSignal()

auto daq::DpmClientImpl::ConnectStorageSignal ( StorageSignal::slot_type const &  slot ) -> boost::signals2::connection

overridevirtual

Connect slot to storage change signal.

DpmClient ensures that signals are only emitted from main thread.

Implements daq::DpmClient.

Definition at line 202 of file dpmClient.cpp.

ScheduleAsync()

auto daq::DpmClientImpl::ScheduleAsync ( std::string const &  spec ) -> boost::future<State>

overridevirtual

Schedule merging.

Implements daq::DpmClient.

Definition at line 96 of file dpmClient.cpp.

StartMonitorStatus()

void daq::DpmClientImpl::StartMonitorStatus ( std::string const &  id )

overridevirtual

Start monitoring DAQ status.

Status is requested:

• Initially
• and rescheduled if reply times out (DPM not running)

Changes are reported via the StatusSignal.

Implements daq::DpmClient.

Definition at line 114 of file dpmClient.cpp.

StopMonitorStatus()

void daq::DpmClientImpl::StopMonitorStatus ( std::string const &  id )

overridevirtual

Stop monitoring DAQ status.

Implements daq::DpmClient.

Definition at line 193 of file dpmClient.cpp.
