Constructor Detail

SendChannelEndpoint

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

Method Detail

decRef

public void decRef()

incRef

public void incRef()

openChannel

public void openChannel(DriverConductorProxy conductorProxy)

originalUriString

public String originalUriString()

statusIndicatorCounterId

public int statusIndicatorCounterId()

indicateActive

public void indicateActive()

closeStatusIndicator

public void closeStatusIndicator()

shouldBeClosed

public boolean shouldBeClosed()

Called by the DriverConductor to determine if the channel endpoint should be closed.

Returns:

true if ready to be closed.

registerForSend

public void registerForSend(NetworkPublication publication)

Called from the Sender to add information to the control packet dispatcher.

Parameters:

publication - to add to the dispatcher

unregisterForSend

public void unregisterForSend(NetworkPublication publication)

Called from the Sender to remove information from the control packet dispatcher.

Parameters:

publication - to remove

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).

Parameters:

buffer - to send

Returns:

number of bytes sent
