io.reactivex.netty.channel

Class AbstractConnectionToChannelBridge<R,W>

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelDuplexHandler

io.reactivex.netty.channel.BackpressureManagingHandler

io.reactivex.netty.channel.AbstractConnectionToChannelBridge<R,W>

Type Parameters:

R - Type read from the connection held by this handler.

W - Type written to the connection held by this handler.

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler

Direct Known Subclasses:

ClientConnectionToChannelBridge

public abstract class AbstractConnectionToChannelBridge<R,W>
extends BackpressureManagingHandler

A bridge between a Connection instance and the associated Channel. All operations on Connection will pass through this bridge to an appropriate action on the Channel

Lazy Connection.getInput() subscription

Lazy subscriptions are allowed on Connection.getInput() if and only if the channel is configured to not read data automatically (i.e. ChannelOption.AUTO_READ is set to false). Otherwise, if Connection.getInput() is subscribed lazily, the subscriber always receives an error. The content in this case is disposed upon reading.
