trait WebSocketBase extends ReadStream[Buffer] with WriteStream[Buffer]

Base WebSocket implementation.

It implements both and so it can be used with io.vertx.scala.core.streams.Pipe to pipe data with flow control.

  2. abstract def binaryHandlerID(): String

    When a WebSocket is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

    When a WebSocket is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

    Given this ID, a different event loop can send a binary frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops. * @return the binary handler id

  3. abstract def binaryMessageHandler(handler: Handler[Buffer]): WebSocketBase

    Set a binary message handler on the connection.

    Set a binary message handler on the connection. This handler serves a similar purpose to io.vertx.scala.core.http.WebSocketBase#handler except that if a message comes into the socket in multiple frames, the data from the frames will be aggregated into a single buffer before calling the handler (using io.vertx.scala.core.http.WebSocketFrame#isFinal to find the boundaries). * @param handler the handler

    When a WebSocket is created it automatically registers an event handler with the eventbus, the ID of that handler is given by textHandlerID.

    Given this ID, a different event loop can send a text frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection.

    Writes a ping frame to the connection. This will be written in a single frame. Ping frames may be at most 125 bytes (octets).

    This method should not be used to write application data and should only be used for implementing a keep alive or to ensure the client is still responsive, see RFC 6455 Section section 5.5.2.
