Constructor & Destructor Documentation

UdpTransport()

UdpTransport::UdpTransport	(	asio::io_context &	context,
		std::uint16_t	port,
		NetworkMetrics &	metrics )

Opens an IPv4 UDP socket bound to a port.

Parameters

context	Asio context that runs the socket handlers.
port	Local port to listen on.
metrics	Counters updated on every send and receive.

Member Function Documentation

send()

void UdpTransport::send	(	const asio::ip::udp::endpoint &	destination,
		const std::vector< std::uint8_t > &	data )

Queues a datagram for sending, ignored if larger than the limit.

Parameters

destination	Address and port of the receiver.
data	Bytes to send.

isOpen()

bool UdpTransport::isOpen

(

)

const

Tells whether the socket is still open.

Returns

True if the socket is open.

setReceiveCallback()

void UdpTransport::setReceiveCallback

(

std::function< void(const asio::ip::udp::endpoint &Endpoint, const std::vector< std::uint8_t > &)>

callback

)

Sets the function called for every received datagram.

Parameters

callback

Receives the sender address and the datagram bytes.
