Method Details

initializeIfNecessary

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

handleRequest

public final CompletionStage<RespRequestHandler> handleRequest(io.netty.channel.ChannelHandlerContext ctx,
 RespCommand type,
 List<byte[]> arguments)

actualHandleRequest

protected CompletionStage<RespRequestHandler> actualHandleRequest(io.netty.channel.ChannelHandlerContext ctx,
 RespCommand type,
 List<byte[]> arguments)

Handles the RESP request returning a stage that when complete notifies the command has completed as well as providing the request handler for subsequent commands.

Implementations should never use the ByteBufAllocator in the context. Instead, they should use allocatorToUse to retrieve a ByteBuffer. This ByteBuffer should only have bytes written to it adding up to the size requested. The ByteBuffer itself should never be written to the context or channel and flush should also never be invoked. Failure to do so may cause mis-ordering or responses as requests support pipelining and a ByteBuf may not be send down stream until later in the pipeline.

Parameters:

ctx - Netty context pipeline for this request

type - The command type

arguments - The remaining arguments to the command

Returns:

stage that when complete returns the new handler to instate. This stage must be completed on the event loop
