Detailed Description

STK internet streaming input class.

This protected Wvin subclass can read streamed data over a network via a TCP socket connection. The data is assumed in big-endian, or network, byte order.

TcpWvIn supports multi-channel data in interleaved format. It is important to distinguish the tick() methods, which return samples produced by averaging across sample frames, from the tickFrame() methods, which return pointers to multi-channel sample frames. For single-channel data, these methods return equivalent values.

This class starts a socket server, which waits for a single remote connection. The default data type for the incoming stream is signed 16-bit integers, though any of the defined STK_FORMATs are permissible.

Constructor & Destructor Documentation

TcpWvIn::TcpWvIn ( int port = 2006 )

Default constructor starts a socket server. If not specified, the server is associated with port 2006. An StkError will be thrown if an error occurs while initializing the input thread or starting the socket server.

---

Member Function Documentation

void TcpWvIn::listen ( unsigned int nChannels = 1, Stk::STK_FORMAT format = STK_SINT16 )

Listen for a (new) connection with specified data channels and format. An StkError will be thrown a socket error or an invalid function argument.

bool TcpWvIn::isConnected ( void )

Returns TRUE is an input connection exists or input data remains in the queue. This method will not return FALSE after an input connection has been closed until all buffered input data has been read out.
