STK internet streaming output class.
This WvOut subclass can stream data over a network via a TCP or UDP socket connection. The data is converted to big-endian byte order, if necessary, before being transmitted.
InetWvOut supports multi-channel data. It is important to distinguish the tick() method that outputs a single sample to all channels in a sample frame from the overloaded one that takes a reference to an StkFrames object for multi-channel and/or multi-frame data.
This class connects to a socket server, the port and IP address of which must be specified as constructor arguments. The default data type is signed 16-bit integers but any of the defined StkFormats are permissible.

unsigned int | nChannels = 1 , |

Overloaded constructor which opens a network connection during instantiation.
An StkError is thrown if a socket error occurs or an invalid argument is specified.

std::string | hostname = "localhost" , |

unsigned int | nChannels = 1 , |
||
Stk::StkFormat | format = STK_SINT16 |
||
) |
Connect to the specified host and port and prepare to stream nChannels of data in the given data format.
An StkError is thrown if a socket error occurs or an invalid argument is specified.
|
virtual |
Output a single sample to all channels in a sample frame.
An StkError is thrown if an output error occurs. If a socket connection does not exist, the function does nothing (a warning will be issued if STK_DEBUG is defined during compilation).
Implements stk::WvOut.
|
virtual |
Output the StkFrames data.
An StkError will be thrown if an output error occurs. An StkError will also be thrown if STK_DEBUG is defined during compilation and there is an incompatability between the number of channels in the FileWvOut object and that in the StkFrames object. If a socket connection does not exist, the function does nothing (a warning will be issued if STK_DEBUG is defined during compilation).
Implements stk::WvOut.
