| A class for receiving OSC data from an OSCReceiver. More...
class | ListenerWithOSCAddress
| A class for receiving only those OSC messages from an OSCReceiver that match a given OSC address. More...
struct | MessageLoopCallback
| Use this struct as the template parameter for Listener and ListenerWithOSCAddress to receive incoming OSC data on the message thread. More...
struct | RealtimeCallback
| Use this struct as the template parameter for Listener and ListenerWithOSCAddress to receive incoming OSC data immediately after it arrives, called directly on the network thread that listens to incoming OSC traffic. More...

## Public Types
using | FormatErrorHandler = std::function<void (const char* data, int dataSize)>

## Detailed Description

A class for receiving OSC data.

An OSCReceiver object allows you to receive OSC bundles and messages. It can connect to a network port, receive incoming OSC packets from the network via UDP, parse them, and forward the included OSCMessage and OSCBundle objects to its listeners.

## Member Typedef Documentation

## ◆ FormatErrorHandler

using OSCReceiver::FormatErrorHandler = std::function<void (const char* data, int dataSize)>

An error handler function for OSC format errors that can be called by the OSCReceiver.

The arguments passed are the pointer to and the data of the buffer that the OSCReceiver has failed to parse.

## Constructor & Destructor Documentation

## ◆ OSCReceiver() [1/2]

OSCReceiver::OSCReceiver | ( |  | ) |

Creates an OSCReceiver.

## ◆ OSCReceiver() [2/2]

OSCReceiver::OSCReceiver | ( | const String & | threadName | ) |

Creates an OSCReceiver with a specific name for its thread.

## ◆ ~OSCReceiver()

OSCReceiver::~OSCReceiver | ( |  | ) |

Destructor.

## Member Function Documentation

## ◆ connect()

bool OSCReceiver::connect | ( | int | portNumber | ) |

Connects to the specified UDP port using a datagram socket, and starts listening to OSC packets arriving on this port.

Returns
  true if the connection was successful; false otherwise.

## ◆ connectToSocket()

bool OSCReceiver::connectToSocket | ( | DatagramSocket & | socketToUse | ) |

Connects to a UDP datagram socket that is already set up, and starts listening to OSC packets arriving on this port.

Make sure that the object you give it doesn't get deleted while this object is still using it!

Returns
  true if the connection was successful; false otherwise.

## ◆ disconnect()

bool OSCReceiver::disconnect | ( |  | ) |

Disconnects from the currently used UDP port.

Returns
  true if the disconnection was successful; false otherwise.

## ◆ addListener() [1/4]

void OSCReceiver::addListener | ( | Listener< MessageLoopCallback > * | listenerToAdd | ) |

Adds a listener that listens to OSC messages and bundles.

This listener will be called on the application's message loop.

## ◆ addListener() [2/4]

void OSCReceiver::addListener | ( | Listener< RealtimeCallback > * | listenerToAdd | ) |

Adds a listener that listens to OSC messages and bundles.

This listener will be called in real-time directly on the network thread that receives OSC data.

## ◆ addListener() [3/4]

void OSCReceiver::addListener | ( | ListenerWithOSCAddress< MessageLoopCallback > * | listenerToAdd,
|  | OSCAddress | addressToMatch )

Adds a filtered listener that listens to OSC messages matching the address used to register the listener here.

The listener will be called on the application's message loop.

## ◆ addListener() [4/4]

void OSCReceiver::addListener | ( | ListenerWithOSCAddress< RealtimeCallback > * | listenerToAdd,
|  | OSCAddress | addressToMatch )

Adds a filtered listener that listens to OSC messages matching the address used to register the listener here.

The listener will be called on the application's message loop.

## ◆ removeListener() [1/4]

void OSCReceiver::removeListener | ( | Listener< MessageLoopCallback > * | listenerToRemove | ) |

Removes a previously-registered listener.

## ◆ removeListener() [2/4]

void OSCReceiver::removeListener | ( | Listener< RealtimeCallback > * | listenerToRemove | ) |

Removes a previously-registered listener.

## ◆ removeListener() [3/4]

void OSCReceiver::removeListener | ( | ListenerWithOSCAddress< MessageLoopCallback > * | listenerToRemove | ) |

Removes a previously-registered listener.

## ◆ removeListener() [4/4]

void OSCReceiver::removeListener | ( | ListenerWithOSCAddress< RealtimeCallback > * | listenerToRemove | ) |

Removes a previously-registered listener.

## ◆ registerFormatErrorHandler()

void OSCReceiver::registerFormatErrorHandler | ( | FormatErrorHandler | handler | ) |

Installs a custom error handler which is called in case the receiver encounters a stream it cannot parse as an OSC bundle or OSC message.

By default (i.e. if you never use this method), in case of a parsing error nothing happens and the invalid packet is simply discarded.
