Detailed Description

A communication socket for the TCP/IP protocol.

#include <Socket.h>

Inheritance diagram for Socket:

Public Member Functions
bool	disconnected ()
	Checks if the connection was lost.
bool	connected ()
	Checks if the connection is open.
bool	bind (const String &ip, int port)
	Binds this socket to the given IP address and port number.
bool	bind (int port)
	Binds this socket with the given port number to all IPv4 interfaces.
void	listen (int n=5)
	Makes this socket listen to incoming connections.
Socket	accept ()
	For a listening socket, waits for an incoming connection and returns a socket to communicate with the remote peer.
InetAddress	remoteAddress () const
	Returns the adress of the remote peer for a connected socket.
InetAddress	localAddress () const
	Returns the adress of this connected socket if bound.
bool	connect (const String &host, int port)
	Connects this socket to the given host name and port, trying all addresses assigned to that name until one succeeds.
bool	connect (const String &host)
	Connects this socket to the given address given as a string "host:port" or "[ipv6]:port".
void	close ()
	Closes this socket.
String	readLine ()
	Reads a line of text from the socket (keep in mind this is not buffered, can be a bit inefficient, and there is a length limit of 8000 bytes)
int	available ()
	Returns the number of bytes available for reading without blocking.
int	read (void *data, int size)
	Reads size bytes from the socket into the bufffer pointed to by data.
int	write (const void *data, int n)
	Writes n bytes from the bufffer pointed to by data to the socket.
int	write (const ByteArray &data)
	Writes the byte array to the socket and returns the number of bytes actually sent.
ByteArray	read (int n=-1)
	Reads n bytes and returns them as an array of bytes, or reads all available bytes if no argument is given.
void	skip (int n)
	Skips (reads and discards) the next n bytes from the socket.
bool	waitInput (double timeout=2)
	Waits until there is incoming data in the socket or it is disconnected for a maximum time, and returns true if some of that happened before timeout.
bool	waitData (double timeout=2)
	Waits until there is incoming data in the socket or it is disconnected for a maximum time, and returns true only if there is data to read (false may mean no data or disconnection)
int	error () const
	Returns true if there was some communication error in this socket.
String	errorMsg () const
	Returns a string representation of the last socket error.
template<class T >
Socket &	operator<< (const T &x)
	Writes variable x to the socket respecting endianness in binary form.
template<class T >
Socket &	operator>> (T &x)
	Reads variable x from the socket respecting endianness in binary form.
String	readString (int n)
	Reads n bytes from the socket a string.
Socket &	operator>> (String &x)
	Reads a string from the socket that is preceded by its length as an int32 (the sender must send the byte length before) More...
