double Navigation::General::Alignment::Task::evaluate ( void  )

inline

Evaluate orientation performance.

void Navigation::General::Alignment::Task::onEntityResolution ( void  )

inlinevirtual

Called when the task is instructed to resolve all the entity identifiers it needs for normal execution.

See resolveEntity(). Derived classes that need to resolve entity identifiers should override this function.

Reimplemented from DUNE::Tasks::Task.

References Navigation::General::Alignment::Arguments::elabel_imu, m_args, m_imu_eid, DUNE::Tasks::Task::resolveEntity(), and DUNE::Tasks::Task::war().

void Navigation::General::Alignment::Task::onMain ( void  )

Implements DUNE::Tasks::Task.

References m_calibrated, m_wdog, DUNE::Tasks::Task::setEntityState(), DUNE::Tasks::Task::stopping(), and DUNE::Tasks::Task::waitForMessages().

void Navigation::General::Alignment::Task::onResourceInitialization ( void  )

inlinevirtual

Called when the task is instructed to initialize resources acquired previously or whose initialization depends on run-time parameters.

Reimplemented from DUNE::Tasks::Task.

References Navigation::General::Alignment::Arguments::avg_samples, m_args, m_avg_acc, m_delay, and reset().

void Navigation::General::Alignment::Task::onResourceRelease ( void  )

inlinevirtual

Called when the task is instructed to release resources.

Derived classes that override this function must not assume that any resource was previously acquired. This function must be implemented in such a way that it can be called at any time.

Reimplemented from DUNE::Tasks::Task.

References m_avg_acc.

void Navigation::General::Alignment::Task::onUpdateParameters ( void  )

inlinevirtual

Called when the task is instructed to update its run-time parameters.

Derived classes that need to compute auxiliary values based on run-time parameters should override this function.

Reimplemented from DUNE::Tasks::Task.

References Navigation::General::Alignment::Arguments::delay, m_args, m_delay, m_wdog, and Navigation::General::Alignment::Arguments::wdog.

void Navigation::General::Alignment::Task::reset ( void  )
