void Vision::Lumenera::Task::onActivation ( void  )
inlinevirtual

Called when the task starts/resumes normal execution.

Reimplemented from DUNE::Tasks::Task.

void Vision::Lumenera::Task::onDeactivation ( void  )
inlinevirtual

Called when the task stops normal execution and enters an idleness state.

Reimplemented from DUNE::Tasks::Task.

void Vision::Lumenera::Task::onMain ( void  )
inlinevirtual
void Vision::Lumenera::Task::onRequestActivation ( void  )
inlinevirtual

Called when an external activation request is received.

Derived classes that need to perform extra steps to prepare normal execution should replace the default behaviour of immediate activation with calls to activate() when the request is completed or activationFailed() if the request cannot be honoured.

Reimplemented from DUNE::Tasks::Task.

References Vision::Lumenera::EntityActivationMaster::activate().

void Vision::Lumenera::Task::onRequestDeactivation ( void  )
inlinevirtual

Called when an external deactivation request is received.

Derived classes that need to perform extra steps to prepare normal execution should replace the default behaviour of immediate deactivation with calls to deactivate() when the request is completed or deactivationFailed() if the request cannot be honoured.

Reimplemented from DUNE::Tasks::Task.

References Vision::Lumenera::EntityActivationMaster::deactivate().

void Vision::Lumenera::Task::onResourceAcquisition ( void  )
inlinevirtual

Called when the task is instructed to acquire resources whose configuration is defined by run-time parameters.

Reimplemented from DUNE::Tasks::Task.

References Vision::Lumenera::Arguments::led_gpio, and Vision::Lumenera::Arguments::pwr_gpio.

void Vision::Lumenera::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.

void Vision::Lumenera::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.
