Constructor & Destructor Documentation

AdaptiveTCPClient()

AdaptiveTCPClient::AdaptiveTCPClient ( QObject * parent = nullptr )

explicit

Constructs the TCP client.

Parameters

[in]

parent

Optional parent QObject.

Member Function Documentation

connectTo()

void * AdaptiveTCPClient::connectTo ( const NDEVRServerInfo & server )

override

Establishes a connection to the specified server.

Parameters

[in]

server

The server information to connect to.

Returns

An opaque pointer to the connection socket.

connectToServer()

void AdaptiveTCPClient::connectToServer	(	const StringView &	host,
		uint04	port )

Initiates a TCP connection to the specified host and port.

Parameters

[in]	host	The hostname or IP address to connect to.
[in]	port	The TCP port number.

disconnectFrom()

virtual void AdaptiveTCPClient::disconnectFrom ( void * socket )

overridevirtual

Disconnects from the specified socket.

Parameters

[in]

socket

The socket to disconnect.

isOpen()

virtual bool AdaptiveTCPClient::isOpen ( void * socket = nullptr ) const

overridevirtual

Checks whether the socket is currently connected.

Parameters

[in]

socket

The socket to check, or nullptr for the default.

Returns

True if the connection is open.

rx()

virtual uint08 AdaptiveTCPClient::rx ( void * socket, NDEVRDataPacket & packet )

overridevirtual

Receives data from the socket into a packet.

Parameters

[in]	socket	The socket to receive from.
[in]	packet	The packet buffer to fill.

Returns

The number of bytes received.

tx()

virtual uint08 AdaptiveTCPClient::tx ( void * socket, NDEVRDataPacket & packet, uint08 size )

overridevirtual

Transmits packet data through the socket.

Parameters

[in]	socket	The socket to send through.
[in]	packet	The packet data to send.
[in]	size	The number of bytes to send.

Returns

The number of bytes sent.

wait()

virtual void AdaptiveTCPClient::wait ( const TimeSpan & span, LogPtr log = nullptr )

overridevirtual

Waits for the specified time span, processing events.

Parameters

[in]	span	The duration to wait.
[in]	log	Optional log for progress reporting.
