virtual bool DUNE::Control::PathController::hasSpecificZControl ( void  ) const
inlinevirtual

Flagging method indicating if controller wishes to handle altitude/depth control.

If not (the default) depth or altitude references will be fired at the start of a path.

Returns
false (at the base class level)

Reimplemented in Control::Path::Height::Task.

void DUNE::Control::PathController::onEntityReservation ( void  )
virtual

Entity reservation callback.

Reimplemented from DUNE::Tasks::Task.

References DUNE::Tasks::Task::reserveEntity().

void DUNE::Control::PathController::onMain ( void  )
virtual
virtual void DUNE::Control::PathController::onPathActivation ( void  )
inlinevirtual

Handler for path control activation.

This is called when path control is activated. By default it does nothing.

Reimplemented in Control::Path::ILOS::Task, Control::Path::VectorField::Task, Control::Path::Aerosonde::Task, Control::Path::Height::Task, and Control::Path::PurePursuit::Task.

virtual void DUNE::Control::PathController::onPathDeactivation ( void  )
inlinevirtual

Handler for path control deactivation.

This is called when path control is deactivated. By default it does nothing.

virtual void DUNE::Control::PathController::onPathStartup ( const IMC::EstimatedState state,
const TrackingState ts 
)
inlinevirtual

Handler for the startup of a new path.

The default handler does nothing and can be overriden. This is called when a new path is started (several paths may be executed between activation and deactivation).

Parameters
statecurrent navigational state.
tsinitial tracking state.

void DUNE::Control::PathController::onResourceAcquisition ( void  )
virtual

On resource aquisition This can be overriden but in that case this parent class implementation MUST be called.

Reimplemented from DUNE::Tasks::Task.

References DUNE::Control::BottomTracker.

void DUNE::Control::PathController::onResourceInitialization ( void  )
virtual

On resource initialization This can be overriden but in that case this parent class implementation MUST be called.

Reimplemented from DUNE::Tasks::Task.

References DUNE::Memory::clear().

void DUNE::Control::PathController::signalError ( const std::string &  msg)

Signal an error.

This method should be used by subclasses to signal an error condition.

Parameters
