Detailed Description

This is a base class for a simple TCP connection.

You should not need to use this class directly.

Constructor & Destructor Documentation

ConnectionTCPBase	(	const LogSink &	logInstance,
		const std::string &	server,
		int	port = -1
	)

Constructs a new ConnectionTCPBase object.

Parameters

logInstance	The log target. Obtain it from ClientBase::logInstance().
server	A server to connect to.
port	The port to connect to. The default of -1 means that XMPP SRV records will be used to find out about the actual host:port.

Note

To properly use this object, you have to set a ConnectionDataHandler using registerConnectionDataHandler(). This is not necessary if this object is part of a 'connection chain', e.g. with ConnectionHTTPProxy.

ConnectionTCPBase	(	ConnectionDataHandler *	cdh,
		const LogSink &	logInstance,
		const std::string &	server,
		int	port = -1
	)

Constructs a new ConnectionTCPBase object.

Parameters

cdh	An ConnectionDataHandler-derived object that will handle incoming data.
logInstance	The log target. Obtain it from ClientBase::logInstance().
server	A server to connect to.
port	The port to connect to. The default of -1 means that SRV records will be used to find out about the actual host:port.

~ConnectionTCPBase ( )

virtual

Virtual destructor

Definition at line 77 of file connectiontcpbase.cpp.

Member Function Documentation

void cleanup ( )

virtual

This function is called after a disconnect to clean up internal state. It is also called by ConnectionBase's destructor.

Reimplemented from ConnectionBase.

Definition at line 165 of file connectiontcpbase.cpp.

void disconnect ( )

virtual

Disconnects an established connection. NOOP if no active connection exists.

Implements ConnectionBase.

Definition at line 84 of file connectiontcpbase.cpp.

void getStatistics ( long int &  totalIn, long int &  totalOut  )

virtual

Returns current connection statistics.

Parameters

totalIn	The total number of bytes received.
totalOut	The total number of bytes sent.

Implements ConnectionBase.

Definition at line 159 of file connectiontcpbase.cpp.

const std::string localInterface ( ) const

virtual

Returns the locally bound IP address.

Returns

The locally bound IP address.

Reimplemented from ConnectionBase.

Definition at line 201 of file connectiontcpbase.cpp.

int localPort ( ) const

virtual

Returns the local port.

Returns

The local port.

Reimplemented from ConnectionBase.

Definition at line 191 of file connectiontcpbase.cpp.

ConnectionError receive ( )

virtual

Use this function to put the connection into 'receive mode', i.e. this function returns only when the connection is terminated.

Returns

Returns a value indicating the disconnection reason.

Implements ConnectionBase.

Definition at line 110 of file connectiontcpbase.cpp.

bool send ( const std::string &  data )

virtual

Use this function to send a string of data over the wire. The function returns only after all data has been sent.

Parameters

data	The data to send.

Returns

True if the data has been sent (no guarantee of receipt), false in case of an error.

Implements ConnectionBase.

Definition at line 121 of file connectiontcpbase.cpp.

void setSocket ( int  socket )

inline

This function allows to set an existing socket with an established connection to use in this connection. You will still need to call connect() in order to negotiate the XMPP stream. You should not set a new socket after having called connect().

Parameters

socket

The existing socket.

Definition at line 99 of file connectiontcpbase.h.

int socket ( ) const

inline

Gives access to the raw socket of this connection. Use it wisely. You can select()/poll() it and use ConnectionTCPBase::recv( -1 ) to fetch the data.

Returns

The socket of the active connection, or -1 if no connection is established.
