Constructor Detail

SendChannelEndpoint

public SendChannelEndpoint(UdpChannel udpChannel,
                           MediaDriver.Context context)

Method Detail

openChannel

public void openChannel()

Called from the Sender to create the channel for the transport.

originalUriString

public java.lang.String originalUriString()

getPublication

public NetworkPublication getPublication(int streamId)

Called from the DriverConductor to find the publication associated with a sessionId and streamId

Parameters:

streamId - for the publication

Returns:

publication

addPublication

public void addPublication(NetworkPublication publication)

Called form the DriverConductor to associate a publication with a sessionId and streamId.

Parameters:

publication - to associate

removePublication

public NetworkPublication removePublication(NetworkPublication publication)

Called from the DriverConductor to remove an association of a publication.

Parameters:

publication - to remove

Returns:

publication removed

sessionCount

public int sessionCount()

Called from the DriverConductor to return the number of associated publications.

Returns:

number of publications associated.

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)

pollForData

public int pollForData()

Description copied from class: UdpChannelTransport

Attempt to receive waiting data.

Specified by:

pollForData in class UdpChannelTransport

Returns:

number of bytes received.

dispatch

protected int dispatch(org.agrona.concurrent.UnsafeBuffer buffer,
                       int length,
                       java.net.InetSocketAddress srcAddress)
