Interface Decoder

All Known Subinterfaces:
Decoder.Binary<T>, Decoder.BinaryStream<T>, Decoder.Text<T>, Decoder.TextStream<T>

public interface Decoder
The Decoder interface holds member interfaces that define how a developer can provide the web socket container a way web socket messages into developer defined custom objects. The websocket implementation creates a new instance of the decoder per endpoint instance per connection. The lifecycle of the Decoder instance is governed by the container calls to the init(javax.websocket.EndpointConfig) and destroy() methods.
