Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected void`	`decode(ChannelHandlerContext ctx, Buffer in)`	Decode the from one `Buffer` to another.
`protected void`	`handlerRemoved0(ChannelHandlerContext ctx)`	Gets called after the `ByteToMessageDecoder` was removed from the actual context and it doesn't handle events anymore.
`protected abstract Future<T>`	`lookup(ChannelHandlerContext ctx, Buffer clientHello)`	Kicks off a lookup for the given `ClientHello` and returns a `Future` which in turn will notify the `onLookupComplete(ChannelHandlerContext, Future)` on completion.
`protected abstract void`	`onLookupComplete(ChannelHandlerContext ctx, Future<? extends T> future)`	Called upon completion of the `lookup(ChannelHandlerContext, Buffer)` `Future`.
`void`	`read(ChannelHandlerContext ctx)`	Intercepts `ChannelHandlerContext.read()`.

  - decode
```
protected void decode(ChannelHandlerContext ctx,
                      Buffer in)
               throws Exception
```
    Description copied from class: ByteToMessageDecoder
    
    Decode the from one Buffer to another. This method will be called till either the input Buffer has nothing to read when return from this method or till nothing was read from the input Buffer.
    
    Specified by:
    
    decode in class ByteToMessageDecoder
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to
    
    in - the Buffer from which to read data
    
    Throws:
    
    Exception - is thrown if an error occurs
  - handlerRemoved0
```
protected void handlerRemoved0(ChannelHandlerContext ctx)
                        throws Exception
```
    Description copied from class: ByteToMessageDecoder
    
    Gets called after the ByteToMessageDecoder was removed from the actual context and it doesn't handle events anymore.
    
    Overrides:
    
    handlerRemoved0 in class ByteToMessageDecoder
    
    Throws:
    
    Exception
  - lookup
```
protected abstract Future<T> lookup(ChannelHandlerContext ctx,
                                    Buffer clientHello)
                             throws Exception
```
    Kicks off a lookup for the given ClientHello and returns a Future which in turn will notify the onLookupComplete(ChannelHandlerContext, Future) on completion. See https://tools.ietf.org/html/rfc5246#section-7.4.1.2
    struct { ProtocolVersion client_version; Random random; SessionID session_id; CipherSuite cipher_suites<2..2^16-2>; CompressionMethod compression_methods<1..2^8-1>; select (extensions_present) { case false: struct {}; case true: Extension extensions<0..2^16-1>; }; } ClientHello;
