Constructor Detail

SendChannelEndpoint

public SendChannelEndpoint(UdpChannel udpChannel,
                           org.agrona.concurrent.status.AtomicCounter statusIndicator,
                           MediaDriver.Context context)

Method Detail

decRef

public int decRef()

incRef

public int incRef()

openChannel

public void openChannel()

originalUriString

public java.lang.String originalUriString()

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(java.nio.ByteBuffer buffer)

Send contents of a ByteBuffer to connected address. This is used on the send size for performance over sentTo().

Parameters:

buffer - to send

Returns:

number of bytes sent

presend

protected void presend(java.nio.ByteBuffer buffer,
                       java.net.InetSocketAddress address)
