 int size)

channelRegistered

public void channelRegistered(io.netty.channel.ChannelHandlerContext ctx)
                       throws Exception

Specified by:

channelRegistered in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelRegistered in class io.netty.channel.ChannelInboundHandlerAdapter

Throws:

Exception

channelUnregistered

public void channelUnregistered(io.netty.channel.ChannelHandlerContext ctx)
                         throws Exception

Specified by:

channelUnregistered in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelUnregistered in class io.netty.channel.ChannelInboundHandlerAdapter

Throws:

Exception

channelReadComplete

public void channelReadComplete(io.netty.channel.ChannelHandlerContext ctx)
                         throws Exception

Specified by:

channelReadComplete in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelReadComplete in class io.netty.handler.codec.ByteToMessageDecoder

Throws:

Exception

channelWritabilityChanged

public void channelWritabilityChanged(io.netty.channel.ChannelHandlerContext ctx)
                               throws Exception

Specified by:

channelWritabilityChanged in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelWritabilityChanged in class io.netty.channel.ChannelInboundHandlerAdapter

Throws:

Exception

attemptReadResume

protected void attemptReadResume(io.netty.channel.ChannelHandlerContext ctx)

handleCommandAndArguments

protected boolean handleCommandAndArguments(io.netty.channel.ChannelHandlerContext ctx,
 RespCommand command,
 List<byte[]> arguments)

Handles the actual command request. This entails passing the command to the request handler and if the request is completed the decoder may parse more commands.

Parameters:

ctx - channel context in use for this command

command - the actual command

arguments - the arguments provided to the command. The list should not be retained as it is reused

Returns:

boolean whether the decoder can read more bytes or must wait

exceptionCaught

public void exceptionCaught(io.netty.channel.ChannelHandlerContext ctx,
 Throwable cause)

Specified by:

exceptionCaught in interface io.netty.channel.ChannelHandler

Specified by:

exceptionCaught in interface io.netty.channel.ChannelInboundHandler

Overrides:

exceptionCaught in class io.netty.channel.ChannelInboundHandlerAdapter
