Constructor Detail

ReceiveDestinationTransport

public ReceiveDestinationTransport(UdpChannel udpChannel,
                                   MediaDriver.Context context,
                                   AtomicCounter localSocketAddressIndicator,
                                   ReceiveChannelEndpoint receiveChannelEndpoint)

Construct transport for a receiving destination.

Parameters:

udpChannel - for the destination.

context - for configuration.

localSocketAddressIndicator - to indicate status of the transport.

receiveChannelEndpoint - to which this destination belongs.

Method Detail

openChannel

public void openChannel(DriverConductorProxy conductorProxy,
                        AtomicCounter statusIndicator)

Open the channel by the receiver.

Parameters:

conductorProxy - for sending instructions by to the driver conductor.

statusIndicator - for the channel.

closeTransport

public void closeTransport()

Close the networking elements of the ReceiveChannelEndpoint, but leave other components (e.g. counters) in place.

closeIndicators

public void closeIndicators()

Close indicator counters associated with the transport.

close

public void close()

Close transport, canceling any pending read operations and closing channel.

Specified by:

close in interface AutoCloseable

Overrides:

close in class UdpChannelTransport

hasExplicitControl

public boolean hasExplicitControl()

Has the channel explicit control address.

Returns:

true if the channel has explicit control address.

explicitControlAddress

public InetSocketAddress explicitControlAddress()

Get the explicit control address for the channel.

Returns:

the explicit control address for the channel if set, otherwise null.

selectionKey

public void selectionKey(SelectionKey key)

Store the SelectionKey for the registered transport.

Parameters:

key - the SelectionKey for the registered transport.

timeOfLastActivityNs

public void timeOfLastActivityNs(long nowNs)

Store the time of last activity for the destination.

Parameters:

nowNs - the time of last activity for the destination.

timeOfLastActivityNs

public long timeOfLastActivityNs()

Get the time of last activity for the destination.

Returns:

the time of last activity for the destination.

udpChannel

public UdpChannel udpChannel()

UdpChannel associated with the destination.

Overrides:

udpChannel in class UdpChannelTransport

Returns:

the UdpChannel associated with the destination.

currentControlAddress

public void currentControlAddress(InetSocketAddress newAddress)

Store the time current control address for the destination.

Parameters:

newAddress - control address for the destination.

currentControlAddress

public InetSocketAddress currentControlAddress()

The current control address for the destination.

Returns:

the time current control address for the destination.
