Constructor Detail

DebugReceiveChannelEndpoint

public DebugReceiveChannelEndpoint(UdpChannel udpChannel,
                                   DataPacketDispatcher dispatcher,
                                   AtomicCounter statusIndicator,
                                   MediaDriver.Context context)

Construct a ReceiveChannelEndpoint with defaults for loss from DebugChannelEndpointConfiguration.

Parameters:

udpChannel - for the media.

dispatcher - for forwarding packets.

statusIndicator - for the endpoint for the channel.

context - for configuration.

DebugReceiveChannelEndpoint

public DebugReceiveChannelEndpoint(UdpChannel udpChannel,
                                   DataPacketDispatcher dispatcher,
