Constructor & Destructor Documentation

◆ StreamSocket() [1/3]

fawkes::StreamSocket::StreamSocket ( float  timeout = 0.f)

Constructor.

This assumes that the socket will later be created using connect().

Parameters
timeouttimeout, if 0 all operationsare blocking, otherwise it is tried for timeout seconds.

Definition at line 52 of file stream.cpp.

Referenced by operator=().

◆ StreamSocket() [2/3]

fawkes::StreamSocket::StreamSocket ( AddrType  addr_type,
float  timeout = 0.f 
)

Constructor.

Parameters
addr_typeSpecify IPv4 or IPv6
timeouttimeout, if 0 all operationsare blocking, otherwise it is tried for timeout seconds.

Definition at line 61 of file stream.cpp.

◆ StreamSocket() [3/3]

fawkes::StreamSocket::StreamSocket ( StreamSocket stream_socket)

Copy constructor.

Parameters
stream_socketsocket to copy.

Definition at line 69 of file stream.cpp.

References fawkes::Socket::operator=().

Member Function Documentation

◆ clone()

Socket * fawkes::StreamSocket::clone ( )
virtual

Clone socket.

Returns
a copied instance of StreamSocket.

Implements fawkes::Socket.

Definition at line 88 of file stream.cpp.

References fawkes::Socket::sock_fd.

◆ nodelay()

bool fawkes::StreamSocket::nodelay ( )

Check if Nalge algorithm is disabled.

This checks the TCP_NODELAY option on the socket. If it is set then the Nagle algorithm is disabled and all data is send out immediately.

Returns
true, if nodelay is enabled and thus the Nagle algorithm disabled, false otherwise

Definition at line 100 of file stream.cpp.

◆ operator=()

StreamSocket & fawkes::StreamSocket::operator= ( StreamSocket s)

Assingment operator.

Parameters
ssocket to copy from
Returns
reference to this

Definition at line 78 of file stream.cpp.

References StreamSocket().

◆ set_nodelay()

void fawkes::StreamSocket::set_nodelay ( bool  nodelay)

Enable or disable Nagle algorithm.

Parameters
nodelaytrue to disable Nagle algorithm, false to enable it
See also
nodelay()
