Member Function Documentation

export_reference_interfaces()

std::vector< hardware_interface::CommandInterface::SharedPtr > controller_interface::ControllerInterface::export_reference_interfaces ( )

finalvirtual

Controller has no reference interfaces.

Returns

empty list.

Implements controller_interface::ControllerInterfaceBase.

export_state_interfaces()

std::vector< hardware_interface::StateInterface::ConstSharedPtr > controller_interface::ControllerInterface::export_state_interfaces ( )

finalvirtual

A non-chainable controller doesn't export any state interfaces.

Returns

empty list.

Implements controller_interface::ControllerInterfaceBase.

is_chainable()

bool controller_interface::ControllerInterface::is_chainable ( ) const

finalvirtual

Controller is not chainable.

Returns

false.

Implements controller_interface::ControllerInterfaceBase.

is_in_chained_mode()

bool controller_interface::ControllerInterface::is_in_chained_mode ( ) const

finalvirtual

Controller can not be in chained mode.

Returns

false.

Implements controller_interface::ControllerInterfaceBase.

set_chained_mode()

bool controller_interface::ControllerInterface::set_chained_mode ( bool  chained_mode )

finalvirtual

Controller is not chainable, therefore no chained mode can be set.

Returns

false.

Implements controller_interface::ControllerInterfaceBase.
