Param()
mavsdk::Param::Param(std::shared_ptr< System > system)
Constructor. Creates the plugin for a specific System.
The plugin is typically created as shown below:
auto param = Param(system);
Parameters
- std::shared_ptr< System > system - The specific system associated with this plugin.
~Param()
mavsdk::Param::~Param()
Destructor (internal use only).
Param()
mavsdk::Param::Param(const Param &other)
Copy constructor.
Parameters
- const Param& other -
