Websocket api
JSR 356, Java API for WebSocket, specifies the API that Java developers can use when they want to integrate WebSockets into their applications—both on the server side as well as on the Java client side. Every implementation of the WebSocket protocol that claims to be compliant with JSR 356 must implement this API. As a consequence, developers can write their WebSocket-based applications …
This API consists of a Protocol Specification and a set of Example programs used to illustrate the usage of the protocol to make websocket connections to Refinitiv Real-Time Distribution Systems*, and, to Refinitiv Real-Time - Optimized (cloud solution) available via Refinitiv Data Platform (RDP). These examples** are built … The Jakarta WebSocket API makes it easy to develop decoders and encoders by simply implementing the Decoder or Encoder interfaces, respectively. Listing 5 shows the Decoder class implementation, which is named MessageDecoder. This class decodes the client-side message into a Message object for processing by the WebSocket server.

To handle it, add an event listener for the message event, or use the onmessage event handler. To begin listening for incoming data, you can do something like this: WebSockets API offers real-time market data updates. WebSockets is a bidirectional protocol offering fastest real-time data, helping you build real-time applications. The public message types presented below do not require authentication. Private-data messages can be subscribed on a separate authenticated endpoint.
