Class WebSocket

java.lang.Object
io.vertx.reactivex.core.http.WebSocket
All Implemented Interfaces:
io.vertx.lang.rx.RxDelegate, WebSocketBase, ReadStream<Buffer>, StreamBase, WriteStream<Buffer>
Direct Known Subclasses:
ClientWebSocket, ServerWebSocket
public class WebSocket extends Object implements io.vertx.lang.rx.RxDelegate, WebSocketBase
Common WebSocket implementation.

It implements both and so it can be used with Pipe to pipe data with flow control.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

      When the data is moved from the queue to the actual medium, the returned will be completed with the write result, e.g the future is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

    • binaryHandlerID

      public String binaryHandlerID()
      When a WebSocket is created, it may register an event handler with the event bus - the ID of that handler is given by this method.

      By default, no handler is registered, the feature must be enabled via WebSocketConnectOptions or HttpServerOptions.

      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.

      Specified by:
      binaryHandlerID in interface WebSocketBase
      Returns:
      the binary handler id

    • textHandlerID

      public String textHandlerID()
      When a WebSocket is created, it may register an event handler with the eventbus, the ID of that handler is given by textHandlerID.

      By default, no handler is registered, the feature must be enabled via WebSocketConnectOptions or HttpServerOptions.

      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. This allows you to write data to other WebSockets which are owned by different event loops.

      Specified by:
      textHandlerID in interface WebSocketBase
      Returns:
      the text handler id

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

      Specified by:
      writePing in interface WebSocketBase
      Parameters:
      data - the data to write, may be at most 125 bytes

    • setWriteQueueMaxSize

      public WebSocket setWriteQueueMaxSize(int maxSize)
      Description copied from interface: WriteStream
      Set the maximum size of the write queue to maxSize. You will still be able to write to the stream even if there is more than maxSize items in the write queue. This is used as an indicator by classes such as Pipe to provide flow control.

      The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

      Specified by:
      setWriteQueueMaxSize in interface WebSocketBase
      Specified by:
      setWriteQueueMaxSize in interface WriteStream<Buffer>

    • drainHandler

      public WebSocket drainHandler(Handler<Void> handler)
      Description copied from interface: WriteStream
      Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.

      The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.

      Specified by:
      drainHandler in interface WebSocketBase
      Specified by:
      drainHandler in interface WriteStream<Buffer>

    • closeHandler

      public WebSocket closeHandler(Handler<Void> handler)
      Description copied from interface: WebSocketBase
      Set a close handler. This will be called when the WebSocket is closed.

      After this callback, no more messages are expected. When the WebSocket received a close frame, the WebSocketBase.closeStatusCode() will return the status code and WebSocketBase.closeReason() will return the reason.

      Specified by:
      closeHandler in interface WebSocketBase
      Parameters:
      handler - the handler
      Returns:
      a reference to this, so the API can be used fluently

    • shutdownHandler

      public WebSocket shutdownHandler(Handler<Void> handler)
      Description copied from interface: WebSocketBase
      Set a handler notified when the WebSocket is shutdown: the client or server will close the connection within a certain amount of time. This gives the opportunity to the handler to close the WebSocket gracefully before the WebSocket is forcefully closed.
      Specified by:
      shutdownHandler in interface WebSocketBase
      Parameters:
      handler - the handler notified with the remaining shutdown
      Returns:
      a reference to this, so the API can be used fluently

    • frameHandler

      public WebSocket frameHandler(Handler<WebSocketFrame> handler)
      Description copied from interface: WebSocketBase
      Set a frame handler on the connection. This handler will be called when frames are read on the connection.
      Specified by:
      frameHandler in interface WebSocketBase
      Parameters:
      handler - the handler
      Returns:
      a reference to this, so the API can be used fluently

    • textMessageHandler

      public WebSocket textMessageHandler(Handler<String> handler)
      Description copied from interface: WebSocketBase
      Set a text message handler on the connection. This handler will be called similar to the WebSocketBase.binaryMessageHandler(Handler), but the buffer will be converted to a String first
      Specified by:
      textMessageHandler in interface WebSocketBase
      Parameters:
      handler - the handler
      Returns:
      a reference to this, so the API can be used fluently

    • binaryMessageHandler

      public WebSocket binaryMessageHandler(Handler<Buffer> handler)
      Description copied from interface: WebSocketBase
      Set a binary message handler on the connection. This handler serves a similar purpose to WebSocketBase.handler(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 WebSocketFrame to find the boundaries).
      Specified by:
      binaryMessageHandler in interface WebSocketBase
      Parameters:
      handler - the handler
      Returns:
      a reference to this, so the API can be used fluently

    • pongHandler

      public WebSocket pongHandler(Handler<Buffer> handler)
      Description copied from interface: WebSocketBase
      Set a pong frame handler on the connection. This handler will be invoked every time a pong frame is received on the server, and can be used by both clients and servers since the RFC 6455 section 5.5.2 and section 5.5.3 do not specify whether the client or server sends a ping.

      Pong frames may be at most 125 bytes (octets).

      There is no ping handler since ping frames should immediately be responded to with a pong frame with identical content

      Pong frames may be received unsolicited.

      Specified by:
      pongHandler in interface WebSocketBase
      Parameters:
      handler - the handler
      Returns:
      a reference to this, so the API can be used fluently
