public interface Encoder

The Encoder interface defines how developers can provide a way to convert their custom objects into web socket messages. The Encoder interface contains subinterfaces that allow encoding algorithms to encode custom objects to: text, binary data, character stream and write to an output stream. The websocket implementation creates a new instance of the encoder per endpoint instance per connection. This means that each encoder instance has at most one calling thread at a time. The lifecycle of the Encoder instance is governed by the container calls to the init(jakarta.websocket.EndpointConfig) and destroy() methods.
