Constructor & Destructor Documentation

◆ TcpServerComponentImpl()

Drv::TcpServerComponentImpl::TcpServerComponentImpl ( const char *const compName )

construct the TcpServer component.

Parameters

compName name of this component

Definition at line 25 of file TcpServerComponentImpl.cpp.

◆ ~TcpServerComponentImpl()

Drv::TcpServerComponentImpl::~TcpServerComponentImpl ( )

Destroy the component.

Definition at line 43 of file TcpServerComponentImpl.cpp.

Member Function Documentation

◆ configure()

SocketIpStatus Drv::TcpServerComponentImpl::configure	(	const char *	hostname,
		const U16	port,
		const U32	send_timeout_seconds = `SOCKET_SEND_TIMEOUT_SECONDS`,
		const U32	send_timeout_microseconds = `SOCKET_SEND_TIMEOUT_MICROSECONDS`,
		FwSizeType	buffer_size = `1024`
	)

Configures the TcpServer settings but does not open the connection.

The TcpServerComponent needs to listen for a remote TCP client. This call configures the hostname, port and send timeouts for that socket connection. This call should be performed on system startup before recv or send are called. Note: hostname must be a dot-notation IP address of the form "x.x.x.x". DNS translation is left up to the user.

Parameters

hostname	ip address of remote tcp server in the form x.x.x.x
port	port of remote tcp server
send_timeout_seconds	send timeout seconds component. Defaults to: SOCKET_TIMEOUT_SECONDS
send_timeout_microseconds	send timeout microseconds component. Must be less than 1000000. Defaults to: SOCKET_TIMEOUT_MICROSECONDS
buffer_size	size of the buffer to be allocated. Defaults to 1024.

Returns: status of the configure

Definition at line 28 of file TcpServerComponentImpl.cpp.

◆ connected()

void Drv::TcpServerComponentImpl::connected ( )

overrideprotectedvirtual

called when the IPv4 system has been connected

Implements Drv::SocketComponentHelper.

Definition at line 75 of file TcpServerComponentImpl.cpp.

◆ getBuffer()

Fw::Buffer Drv::TcpServerComponentImpl::getBuffer ( )

overrideprotectedvirtual

returns a buffer to fill with data

Gets a reference to a buffer to fill with data. This allows the component to determine how to provide a buffer and the socket read task just fills said buffer.

Returns: Fw::Buffer to fill with data

Implements Drv::SocketComponentHelper.

Definition at line 57 of file TcpServerComponentImpl.cpp.

◆ getListenPort()

U16 Drv::TcpServerComponentImpl::getListenPort ( )

get the port being listened on

Most useful when listen was configured to use port "0", this will return the port used for listening after a port has been determined. Will return 0 if the connection has not been setup.

Returns: receive port

Definition at line 49 of file TcpServerComponentImpl.cpp.

◆ getSocketHandler()

IpSocket & Drv::TcpServerComponentImpl::getSocketHandler ( )

overrideprotectedvirtual

returns a reference to the socket handler

Gets a reference to the current socket handler in order to operate generically on the IpSocket instance. Used for receive, and open calls. This socket handler will be a TcpServer.

Returns: IpSocket reference

Implements Drv::SocketComponentHelper.

Definition at line 53 of file TcpServerComponentImpl.cpp.

◆ isStarted()

bool Drv::TcpServerComponentImpl::isStarted ( )

is started

Definition at line 81 of file TcpServerComponentImpl.cpp.

◆ readLoop()

void Drv::TcpServerComponentImpl::readLoop ( )

overrideprotectedvirtual

read from the socket, overridden to start and terminate the server socket

Reimplemented from Drv::SocketComponentHelper.

Definition at line 102 of file TcpServerComponentImpl.cpp.

◆ sendBuffer()

void Drv::TcpServerComponentImpl::sendBuffer	(	Fw::Buffer	buffer,
		SocketIpStatus	status
	)

overrideprotectedvirtual

sends a buffer to be filled with data

Sends the buffer gotten by getBuffer that has now been filled with data. This is used to delegate to the component how to send back the buffer. Ignores buffers with error status error.

Returns: Fw::Buffer filled with data to send out

Implements Drv::SocketComponentHelper.

Definition at line 61 of file TcpServerComponentImpl.cpp.

◆ startup()

SocketIpStatus Drv::TcpServerComponentImpl::startup ( )

startup the server socket for communications

Start up the server socket by listening on a port. Note: does not accept clients, this is done in open to facilitate re-connection of clients.

Definition at line 86 of file TcpServerComponentImpl.cpp.

◆ terminate()

void Drv::TcpServerComponentImpl::terminate ( )

terminate the server socket

Close the server socket. Should be done after all clients are shutdown and closed.

Definition at line 96 of file TcpServerComponentImpl.cpp.
