WebSocketDecoder (Yamcs :: Core 5.4.2 API)

All Known Implementing Classes:

JsonDecoder
```
public interface WebSocketDecoder
```
Used to indicate to the WebSocketServerHandler what type of message can be decoded in a specific media representation.
Current implementations need to at least support decoding the envelope, and are assumed to support all operations. In the future, we could break the API in two (1. envelope, 2. payload) if we ever get to a point of needing that.

Method Summary

Modifier and Type	Method	Description
`WebSocketDecodeContext`	`decodeMessage(io.netty.buffer.ByteBuf binary)`	Decodes the common wrapper fields of an incoming web socket message.

- Method Detail
  - decodeMessage
```
WebSocketDecodeContext decodeMessage(io.netty.buffer.ByteBuf binary)
                              throws WebSocketException
```
    Decodes the common wrapper fields of an incoming web socket message. The actual data can be set implementation-specific and does not necessarily need to be processed here, since a second call will be made with an appropriately determined schema.
    
    Throws:
    
    WebSocketException
  - decodeMessageData
```
<T extends com.google.protobuf.Message.Builder> T decodeMessageData(WebSocketDecodeContext ctx,
                                                                    T builder)
                                                             throws WebSocketException
```
    Decodes any data that may be wrapped by the incoming web socket message
    
    Throws:
    
    WebSocketException
