class Net_API StreamSocket: public Socket
This class provides an interface to a
TCP stream socket.
{
public:
StreamSocket();
Creates an unconnected stream socket.
Before sending or receiving data, the socket
must be connected with a call to connect().
StreamSocket(const SocketAddress& address);
Creates a stream socket and connects it to
the socket specified by address.
StreamSocket(const Socket& socket);
Creates the StreamSocket with the SocketImpl
from another socket. The SocketImpl must be
a StreamSocketImpl, otherwise an InvalidArgumentException
will be thrown.
virtual ~StreamSocket();
Destroys the StreamSocket.
StreamSocket& operator = (const Socket& socket);
Assignment operator.
Releases the socket's SocketImpl and
attaches the SocketImpl from the other socket and
increments the reference count of the SocketImpl.
void connect(const SocketAddress& address);
Initializes the socket and establishes a connection to
the TCP server at the given address.
Can also be used for UDP sockets. In this case, no
connection is established. Instead, incoming and outgoing
packets are restricted to the specified address.
void connect(const SocketAddress& address, const Poco::Timespan& timeout);
Initializes the socket, sets the socket timeout and
establishes a connection to the TCP server at the given address.
void connectNB(const SocketAddress& address);
Initializes the socket and establishes a connection to
the TCP server at the given address. Prior to opening the
connection the socket is set to nonblocking mode.
void shutdownReceive();
Shuts down the receiving part of the socket connection.
void shutdownSend();
Shuts down the sending part of the socket connection.
void shutdown();
Shuts down both the receiving and the sending part
of the socket connection.
int sendBytes(const void* buffer, int length, int flags = 0);
Sends the contents of the given buffer through
the socket.
Returns the number of bytes sent, which may be
less than the number of bytes specified.
int receiveBytes(void* buffer, int length, int flags = 0);
Receives data from the socket and stores it
in buffer. Up to length bytes are received.
Returns the number of bytes received.
A return value of 0 means a graceful shutdown
of the connection from the peer.
Throws a TimeoutException if a receive timeout has
been set and nothing is received within that interval.
Throws a NetException (or a subclass) in case of other errors.
void sendUrgent(unsigned char data);
Sends one byte of urgent data through
the socket.
The data is sent with the MSG_OOB flag.
The preferred way for a socket to receive urgent data
is by enabling the SO_OOBINLINE option.
public:
StreamSocket(SocketImpl* pImpl);
Creates the Socket and attaches the given SocketImpl.
The socket takes owership of the SocketImpl.
The SocketImpl must be a StreamSocketImpl, otherwise
an InvalidArgumentException will be thrown.
