Constructor Detail

DebugSendChannelEndpoint

public DebugSendChannelEndpoint(UdpChannel udpChannel,
                                AtomicCounter statusIndicator,
                                MediaDriver.Context context)

Construct a SendChannelEndpoint with defaults for loss from DebugChannelEndpointConfiguration.

Parameters:

udpChannel - for the media.

statusIndicator - for the endpoint for the channel.

context - for configuration.

DebugSendChannelEndpoint

public DebugSendChannelEndpoint(UdpChannel udpChannel,
                                AtomicCounter statusIndicator,
                                MediaDriver.Context context,
                                LossGenerator dataLossGenerator,
                                LossGenerator controlLossGenerator)

Construct a SendChannelEndpoint with configuration for loss rate and seed.

Parameters:

udpChannel - for the media.

statusIndicator - for the endpoint for the channel.

context - for configuration.

dataLossGenerator - for the random loss on the data stream.

controlLossGenerator - for the random loss on the control stream.

Method Detail

send

public int send(ByteBuffer buffer)

Send contents of a ByteBuffer to connected address. This is used on the sender side for performance over send(ByteBuffer, SocketAddress).

Overrides:

send in class SendChannelEndpoint

Parameters:

buffer - to send

Returns:

number of bytes sent

onStatusMessage

public void onStatusMessage(StatusMessageFlyweight msg,
                            UnsafeBuffer buffer,
                            int length,
                            InetSocketAddress srcAddress)

Callback back handler for received status messages.

Overrides:

onStatusMessage in class SendChannelEndpoint

Parameters:

msg - flyweight over the status message.

buffer - containing the message.

length - of the message.

srcAddress - of the message.

onNakMessage

public void onNakMessage(NakFlyweight msg,
                         UnsafeBuffer buffer,
                         int length,
                         InetSocketAddress srcAddress)

Callback back handler for received NAK messages.

Overrides:

onNakMessage in class SendChannelEndpoint

Parameters:

msg - flyweight over the NAK message.

buffer - containing the message.

length - of the message.

srcAddress - of the message.

onRttMeasurement

public void onRttMeasurement(RttMeasurementFlyweight msg,
                             UnsafeBuffer buffer,
                             int length,
                             InetSocketAddress srcAddress)

Callback back handler for received RTT Measurement messages.

Overrides:

onRttMeasurement in class SendChannelEndpoint

Parameters:

msg - flyweight over the RTT message.

buffer - containing the message.

length - of the message.

srcAddress - of the message.
