## Interface WebSocket.FrameConnection

- All Superinterfaces:
    WebSocket.Connection
  All Known Implementing Classes:
    WebSocketConnectionD00, WebSocketServletConnectionD00
  Enclosing interface:
    WebSocket

      public static interface WebSocket.FrameConnection
      extends WebSocket.Connection

  Frame Level Connection

  The Connection interface at the level of sending/receiving frames rather than messages. Also contains methods to decode/generate flags and opcodes without using constants, so that code can be written to work with multiple drafts of the protocol.
