package com.neovisionaries.ws.client

High-quality WebSocket client implementation in Java. This implementation

• complies with RFC 6455 (The WebSocket Protocol),
• works on Java SE 1.5+ and Android,
• supports all the frame types (continuation, binary, text, close, ping and pong),
• provides a method to send a fragmented frame in addition to methods for unfragmented frames,
• provides a method to get the underlying raw socket of a WebSocket to configure it,
• provides a method for Basic Authentication,
• provides a factory class which utilizes SocketFactory interface,
• provides a rich listener interface to hook WebSocket events,
• has fine-grained error codes for fine-grained controllability on errors,
• allows to disable validity checks on RSV1/RSV2/RSV3 bits and opcode of frames,
• supports HTTP proxy, especially "Secure WebSocket" (wss) through "Secure Proxy" (https),
• and supports RFC 7692 (Compression Extensions for WebSocket), also known as permessage-deflate (not enabled by default).

See the description of WebSocket class for usage. The source code is hosted at GitHub.
