UDPCommsDelegate

@protocol UDPCommsDelegate <NSObject>

Callback methods for delegate of a UDPEndpoint object.

  • Called after successfully receiving data. On a server object this data will automatically be echoed back to the sender.

    Declaration

    Objective-C

    - (void)didReceiveData:(NSData *)data fromAddress:(NSData *)addr;

    Swift

    optional func didReceive(_ data: Data!, fromAddress addr: Data!)

    Parameters

    data
    • bytes received.
    addr
    • an NSData containing some form of (struct sockaddr), specifically a (struct sockaddr_in) or (struct sockaddr_in6)

  • Called after a failure to receive data.

    Declaration

    Objective-C

    - (void)didReceiveError:(NSError *)error;

    Swift

    optional func didReceiveError(_ error: Error!)

    Parameters

    error
    • error description

  • Called after successfully sending data.

    Declaration

    Objective-C

    - (void)didSendData:(NSData *)data toAddress:(NSData *)addr;

    Swift

    optional func didSend(_ data: Data!, toAddress addr: Data!)

    Parameters

    data
    • bytes to send.
    addr
    • an NSData containing some form of (struct sockaddr), specifically a (struct sockaddr_in) or (struct sockaddr_in6)

  • Called after a failure to send data.

    Declaration

    Objective-C

    - (void)didFailToSendData:(NSData *)data
                toAddress:(NSData *)addr
                    error:(NSError *)error;

    Swift

    optional func didFail(toSend data: Data!, toAddress addr: Data!, error: Error!)

    Parameters

    data
    • bytes to send.
    addr
    • an NSData containing some form of (struct sockaddr), specifically a (struct sockaddr_in) or (struct sockaddr_in6)

  • Called after the object has successfully started up. On the client addresses is the list of addresses associated with the host name passed to -startConnectedToHostName:port:. On the server, this is the local address to which the server is bound.

    Declaration

    Objective-C

    - (void)didStartWithAddress:(NSData *)address;

    Swift

    optional func didStart(withAddress address: Data!)

    Parameters

    address
    • an NSData containing some form of (struct sockaddr) e.g. a (struct sockaddr_in) or (struct sockaddr_in6)

  • Called after the object stops spontaneously (that is, after some sort of failure, but now after a call to -stop).

    Declaration

    Objective-C

    - (void)didStopWithError:(NSError *)error;

    Swift

    optional func didStopWithError(_ error: Error!)

    Parameters

    error
    • error description
