io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

software.amazon.awssdk.http.nio.netty.internal.UnusedChannelExceptionHandler

All Implemented Interfaces:

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

@ChannelHandler.Sharable
public final class UnusedChannelExceptionHandler
extends io.netty.channel.ChannelInboundHandlerAdapter

A handler for exceptions occurring on channels not current in use (according to ChannelAttributeKey.IN_USE). This does nothing if the channel is currently in use. If it's not currently in use, it will close the channel and log an appropriate notification. This prevents spamming customer logs when errors (eg. connection resets) occur on an unused channel.
