Detailed Description

supports a task to read a given socket adaptation

Defines an Os::Task task to read a socket and send out the data. This represents the task itself, which is capable of reading the data from the socket, sending the data out, and reopening the connection should a non-retry error occur.

Definition at line 27 of file SocketReadTask.hpp.

Constructor & Destructor Documentation

◆ SocketReadTask()

Drv::SocketReadTask::SocketReadTask ( )

constructs the socket read task

Definition at line 22 of file SocketReadTask.cpp.

◆ ~SocketReadTask()

Drv::SocketReadTask::~SocketReadTask ( )

virtual

destructor of the socket read task

Definition at line 24 of file SocketReadTask.cpp.

Member Function Documentation

◆ close()

void Drv::SocketReadTask::close ( )

close the socket communications

Typically stopping the socket read task will shutdown the connection. However, in cases where the read task will not be started, this function may be used to close the socket. This calls a full close on the client socket.

Note: this just delegates to the handler

Definition at line 57 of file SocketReadTask.cpp.

◆ connected()

virtual void Drv::SocketReadTask::connected ( )

protectedpure virtual

called when the IPv4 system has been connected

Implemented in Drv::UdpComponentImpl, Drv::TcpServerComponentImpl, and Drv::TcpClientComponentImpl.

◆ getBuffer()

virtual Fw::Buffer Drv::SocketReadTask::getBuffer ( )

protectedpure virtual

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.

Note: this must be implemented by the inheritor

Returns: Fw::Buffer to fill with data

Implemented in Drv::UdpComponentImpl, Drv::TcpServerComponentImpl, and Drv::TcpClientComponentImpl.

◆ getSocketHandler()

virtual IpSocket& Drv::SocketReadTask::getSocketHandler ( )

protectedpure virtual

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.

Note: this must be implemented by the inheritor

Returns: IpSocket reference

Implemented in Drv::UdpComponentImpl, Drv::TcpServerComponentImpl, and Drv::TcpClientComponentImpl.

◆ join()

Os::Task::Status Drv::SocketReadTask::join ( )

joins to the stopping read task to wait for it to close

Called to join with the read socket task. This will block and return after the task has been stopped with a call to the stopSocketTask method.

Parameters

value_ptr a pointer to fill with data. Passed to the Os::Task::join call. NULL to ignore.

Returns: : Os::Task::Status passed back from the Os::Task::join call.

Definition at line 61 of file SocketReadTask.cpp.

◆ open()

SocketIpStatus Drv::SocketReadTask::open ( )

open the socket for communications

Typically the socket read task will open the connection and keep it open. However, in cases where the read task will not be started, this function may be used to open the socket.

Note: this just delegates to the handler

Returns: status of open, SOCK_SUCCESS for success, something else on error

Definition at line 44 of file SocketReadTask.cpp.

◆ readTask()

void Drv::SocketReadTask::readTask ( void * pointer )

staticprotected

a task designed to read from the socket and output incoming data

Parameters

pointer pointer to "this" component

Definition at line 70 of file SocketReadTask.cpp.

◆ sendBuffer()

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

protectedpure virtual

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.

Note: this must be implemented by the inheritor

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

Implemented in Drv::UdpComponentImpl, Drv::TcpServerComponentImpl, and Drv::TcpClientComponentImpl.

◆ shutdown()

void Drv::SocketReadTask::shutdown ( )

shutdown the socket communications

Typically stopping the socket read task will shutdown the connection. However, in cases where the read task will not be started, this function may be used to close the socket. This calls a full shutdown on the client socket.

Note: this just delegates to the handler

Definition at line 53 of file SocketReadTask.cpp.

◆ start()

void Drv::SocketReadTask::start	(	const Fw::StringBase &	name,
		const bool	reconnect = `true`,
		const Os::Task::ParamType	priority = `Os::Task::TASK_DEFAULT`,
		const Os::Task::ParamType	stack = `Os::Task::TASK_DEFAULT`,
		const Os::Task::ParamType	cpuAffinity = `Os::Task::TASK_DEFAULT`
	)

start the socket read task to start producing data

Starts up the socket reading task and opens socket. This should be called before send calls are expected to work. Will connect to the previously configured port and host. priority, stack, and cpuAffinity are provided to the Os::Task::start call.

Parameters

name	name of the task
reconnect	automatically reconnect socket when closed. Default: true.
priority	priority of the started task. See: Os::Task::start. Default: TASK_DEFAULT, not prioritized
stack	stack size provided to the task. See: Os::Task::start. Default: TASK_DEFAULT, posix threads default
cpuAffinity	cpu affinity provided to task. See: Os::Task::start. Default: TASK_DEFAULT, don't care

Definition at line 26 of file SocketReadTask.cpp.

◆ startup()

SocketIpStatus Drv::SocketReadTask::startup ( )

startup the socket for communications

Status of the socket handler.

Note: this just delegates to the handler

Returns: status of open, SOCK_SUCCESS for success, something else on error

Definition at line 40 of file SocketReadTask.cpp.

◆ stop()

void Drv::SocketReadTask::stop ( )

stop the socket read task and close the associated socket.

Called to stop the socket read task. It is an error to call this before the thread has been started using the startSocketTask call. This will stop the read task and close the client socket.

Definition at line 65 of file SocketReadTask.cpp.
