Class DynamicAddressConnectHandler

java.lang.Object

io.netty5.handler.address.DynamicAddressConnectHandler

All Implemented Interfaces:

ChannelHandler

public abstract class DynamicAddressConnectHandler
extends Object
implements ChannelHandler

ChannelHandler implementation which allows to dynamically replace the used remoteAddress and / or localAddress when making a connection attempt.

This can be useful to for example bind to a specific NetworkInterface based on the remoteAddress.

Method Detail

connect

public final Future<Void> connect(ChannelHandlerContext ctx,
                                  SocketAddress remoteAddress,
                                  SocketAddress localAddress)

Description copied from interface: ChannelHandler

Called once a connect operation is made.

Specified by:

connect in interface ChannelHandler

Parameters:

ctx - the ChannelHandlerContext for which the connect operation is made

remoteAddress - the SocketAddress to which it should connect

localAddress - the SocketAddress which is used as source on connect

Returns:

the Future which will be notified once the operation completes.

localAddress

protected SocketAddress localAddress(SocketAddress remoteAddress,
                                     SocketAddress localAddress)
                              throws Exception

Returns the local SocketAddress to use for ChannelOutboundInvoker.connect(SocketAddress, SocketAddress) based on the original remoteAddress and localAddress. By default, this method returns the given localAddress.

Throws:

Exception

remoteAddress

protected SocketAddress remoteAddress(SocketAddress remoteAddress,
                                      SocketAddress localAddress)
                               throws Exception

Returns the remote SocketAddress to use for ChannelOutboundInvoker.connect(SocketAddress, SocketAddress) based on the original remoteAddress and localAddress. By default, this method returns the given remoteAddress.

Throws:

Exception
