ControlDataSender

A ControlDataSender can send control signals to one or more receivers using a network connection. A single ControlDataSender can connect to multiple receivers, all identified by a UUID. The class is controlled using an ISystemControllerInterface; this interface is responsible for setting up connections to receivers. The ControlDataSender can send asynchronous requests to (all) the receivers and get a response back. Each response is identified with a request ID as well as the UUID of the responding receiver. The ControlDataSender can also receive status messages from the receivers.

Public Functions

	Name
	ControlDataSender() Default constructor, creates an empty object.
	~ControlDataSender() Destructor. Will disconnect from the connected receivers and close the System controller connection.
bool	configure(const std::shared_ptr< ISystemControllerInterface > & controllerInterface, const Settings & settings) Configure this ControlDataSender and connect it to the System Controller. This method will fail in case the ISystemControllerInterface has already been connected to the controller by another component, as such interface can only be used by one component.
bool	sendRequestToReceivers(const std::vector< uint8_t > & request, uint64_t & requestId) Send a request to all the connected ControlDataReceivers asynchronously. The responses will be sent to the response callback.
	ControlDataSender(ControlDataSender const & ) =delete
ControlDataSender &	operator=(ControlDataSender const & ) =delete
std::string	getVersion() Get application version.
std::string	getGitRevision() Get git revision which application was built on.
std::string	getBuildInfo() Get application build information.

Public Functions Documentation

function ControlDataSender

ControlDataSender()

Default constructor, creates an empty object.

function ~ControlDataSender

~ControlDataSender()

Destructor. Will disconnect from the connected receivers and close the System controller connection.

function configure

bool configure(
    const std::shared_ptr< ISystemControllerInterface > & controllerInterface,
    const Settings & settings
)

Configure this ControlDataSender and connect it to the System Controller. This method will fail in case the ISystemControllerInterface has already been connected to the controller by another component, as such interface can only be used by one component.

Parameters:

controllerInterface The interface to the System controller, used for communicating with this ControlDataSender
settings The Settings to use for this ControlDataSender

Return: True on success, false otherwise

function sendRequestToReceivers

bool sendRequestToReceivers(
    const std::vector< uint8_t > & request,
    uint64_t & requestId
)

Send a request to all the connected ControlDataReceivers asynchronously. The responses will be sent to the response callback.

Parameters:

request The request message
requestId The unique identifier of this request. Used to identify the async responses.

Return: True if the request was successfully sent, false otherwise

function ControlDataSender

ControlDataSender(
    ControlDataSender const & 
) =delete

function operator=

ControlDataSender & operator=(
    ControlDataSender const & 
) =delete

function getVersion

static std::string getVersion()

Get application version.

Return: a string with the current version, e.g. “1.0.0”

function getGitRevision

static std::string getGitRevision()

Get git revision which application was built on.

Return: a string with the current git revision, e.g. “v2.1.0-231-gcd012ab”, followed by “-dirty” in case there are changes made to the Git repo.

function getBuildInfo

static std::string getBuildInfo()

Get application build information.

Return: a string with the current build information such as git hashes of all direct dependencies
