Encoder (Java(TM) EE 7 Specification APIs) (original) (raw)

• All Known Subinterfaces:
  Encoder.Binary, Encoder.BinaryStream, Encoder.Text, Encoder.TextStream

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 theinit(javax.websocket.EndpointConfig) and destroy() methods.

  All Methods Instance Methods Abstract Methods

  Modifier and Type	Method and Description
  void	destroy() This method is called when the encoder is about to be removed from service in order that any resources the encoder used may be closed gracefully.
  void	init(EndpointConfig config) This method is called with the endpoint configuration object of the endpoint this encoder is intended for when it is about to be brought into service.

• • Method Detail

     * #### init  
     void init([EndpointConfig](../../javax/websocket/EndpointConfig.html "interface in javax.websocket") config)  
     This method is called with the endpoint configuration object of the endpoint this encoder is intended for when it is about to be brought into service.  
     Parameters:  
     `config` \- the endpoint configuration object when being brought into service  
     * #### destroy  
     void destroy()  
     This method is called when the encoder is about to be removed from service in order that any resources the encoder used may be closed gracefully.
