Detailed Description

A mocked Sock alternative that returns a statically contained data upon read and succeeds and ignores all writes.

The data to be returned is given to the constructor and when it is exhausted an EOF is returned by further reads.

Member Function Documentation

◆ Accept()

std::unique_ptr< Sock > StaticContentsSock::Accept	(	sockaddr *	addr,
		socklen_t *	addr_len
	)		const

inlineoverridevirtual

accept(2) wrapper.

Equivalent to std::make_unique<Sock>(accept(m_socket, addr, addr_len)). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation. The returned unique_ptr is empty if accept() failed in which case errno will be set.

Reimplemented from Sock.

Definition at line 174 of file net.h.

◆ Bind()

int StaticContentsSock::Bind	(	const sockaddr *	addr,
		socklen_t	addr_len
	)		const

inlineoverridevirtual

bind(2) wrapper.

Equivalent to bind(m_socket, addr, addr_len). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 170 of file net.h.

◆ Connect()

int StaticContentsSock::Connect	(	const sockaddr *	addr,
		socklen_t	addr_len
	)		const

inlineoverridevirtual

connect(2) wrapper.

Equivalent to connect(m_socket, addr, addrlen). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 168 of file net.h.

◆ GetSockName()

int StaticContentsSock::GetSockName	(	sockaddr *	name,
		socklen_t *	name_len
	)		const

inlineoverridevirtual

getsockname(2) wrapper.

Equivalent to getsockname(m_socket, name, name_len). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 199 of file net.h.

◆ GetSockOpt()

int StaticContentsSock::GetSockOpt	(	int	level,
		int	opt_name,
		void *	opt_val,
		socklen_t *	opt_len
	)		const

inlineoverridevirtual

getsockopt(2) wrapper.

Equivalent to getsockopt(m_socket, level, opt_name, opt_val, opt_len). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 191 of file net.h.

◆ IsConnected()

bool StaticContentsSock::IsConnected ( std::string & errmsg ) const

inlineoverridevirtual

Check if still connected.

Parameters

[out] errmsg The error string, if the socket has been disconnected.

Returns: true if connected

Reimplemented from Sock.

Definition at line 228 of file net.h.

◆ IsSelectable()

bool StaticContentsSock::IsSelectable ( ) const

inlineoverridevirtual

Check if the underlying socket can be used for select(2) (or the Wait() method).

Returns: true if selectable

Reimplemented from Sock.

Definition at line 207 of file net.h.

◆ Listen()

int StaticContentsSock::Listen ( int backlog ) const

inlineoverridevirtual

listen(2) wrapper.

Equivalent to listen(m_socket, backlog). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 172 of file net.h.

◆ operator=()

StaticContentsSock & StaticContentsSock::operator= ( Sock && other )

inlineoverridevirtual

Move assignment operator, grab the socket from another object and close ours (if set).

Reimplemented from Sock.

Definition at line 150 of file net.h.

Here is the call graph for this function:

◆ Recv()

ssize_t StaticContentsSock::Recv	(	void *	buf,
		size_t	len,
		int	flags
	)		const

inlineoverridevirtual

recv(2) wrapper.

Equivalent to recv(m_socket, buf, len, flags);. Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

bool StaticContentsSock::SetNonBlocking ( ) const

inlineoverridevirtual

Set the non-blocking option on the socket.

Returns: true if set successfully

		socklen_t	opt_len
	)		const

inlineoverridevirtual

setsockopt(2) wrapper.

Equivalent to setsockopt(m_socket, level, opt_name, opt_val, opt_len). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation.

Reimplemented from Sock.

Definition at line 197 of file net.h.

◆ Wait()

bool StaticContentsSock::Wait	(	std::chrono::milliseconds	timeout,
		Event	requested,
		Event *	occurred = `nullptr`
	)		const

inlineoverridevirtual

Wait for readiness for input (recv) or output (send).

Parameters

[in]	timeout	Wait this much for at least one of the requested events to occur.
[in]	requested	Wait for those events, bitwise-or of `RECV` and `SEND`.
[out]	occurred	If not nullptr and the function returns `true`, then this indicates which of the requested events occurred (`ERR` will be added, even if not requested, if an exceptional event occurs on the socket). A timeout is indicated by return value of `true` and `occurred` being set to 0.

Returns: true on success (or timeout, if occurred of 0 is returned), false otherwise

Reimplemented from Sock.

Definition at line 209 of file net.h.

◆ WaitMany()

bool StaticContentsSock::WaitMany	(	std::chrono::milliseconds	timeout,
		EventsPerSock &	events_per_sock
	)		const

inlineoverridevirtual

Same as Wait(), but wait on many sockets within the same timeout.

Parameters

[in]	timeout	Wait this long for at least one of the requested events to occur.
[in,out]	events_per_sock	Wait for the requested events on these sockets and set `occurred` for the events that actually occurred.

Returns: true on success (or timeout, if all what[].occurred are returned as 0), false otherwise
