The ``std::unordered_map<>`` are divided into ``type_state_interfaces_`` and ``type_command_interfaces_`` where type can be: ``joint``, ``sensor``, ``gpio`` and ``unlisted``. E.g. the ``CommandInterfaces`` for all joints can be found in the ``joint_command_interfaces_`` map. The ``unlisted`` includes all interfaces not listed in the ``ros2_control`` XML-tag but were created by overriding the ``export_unlisted_command_interfaces()`` or ``export_unlisted_state_interfaces()`` function by creating some custom ``Command-/StateInterfaces``. + + +ros2controlcli +************** +* Spawner colours were added to ``list_controllers`` depending upon active or inactive (`#1409 `_) +* The ``set_hardware_component_state`` verb was added (`#1248 `_).
