## Interface WebSocketBase

- All Superinterfaces:
    ReadStream<Buffer>, StreamBase, WriteStream<Buffer>
  All Known Implementing Classes:
    ServerWebSocket, WebSocket

      public interface WebSocketBase
      extends ReadStream<Buffer>, WriteStream<Buffer>

  Base WebSocket implementation.

  It implements both and so it can be used with `Pump` to pump data with flow control.

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

    - #### write

          WebSocketBase write(Buffer data)

      Description copied from interface: `WriteStream`
      Write some data to the stream. The data is put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the `WriteStream.writeQueueFull()` method before writing. This is done automatically if using a `Pump`.
      Specified by:
        `write` in interface `WriteStream<Buffer>`
      Parameters:
        `data` - the data to write
      Returns:

    - #### setWriteQueueMaxSize

          WebSocketBase 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 `Pump` to provide flow control.

      The value is defined by the implementation of the stream, e.g in bytes for a `NetSocket`, the number of `Message` for a `MessageProducer`, etc...
      Specified by:
        `setWriteQueueMaxSize` in interface `WriteStream<Buffer>`
      Parameters:
        `maxSize` - the max size of the write stream
      Returns:
        a reference to this, so the API can be used fluently

    - #### drainHandler

          WebSocketBase 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 `Pump` 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 `WriteStream<Buffer>`
      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### binaryHandlerID

          String binaryHandlerID()

      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.

      Returns:
        the binary handler id

    - #### textHandlerID

          String textHandlerID()

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

      Returns:

    - #### subProtocol

          String subProtocol()

      Returns the websocket sub protocol selected by the websocket handshake.

      On the server, the value will be `null` when the handler receives the websocket callback as the handshake will not be completed yet.
      Returns:

    - #### writeFrame

      Returns:
        a reference to this, so the API can be used fluently

    - #### writePing

          WebSocketBase writePing(Buffer data)

      Writes a ping 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 5.5.2.

      There is no pingHandler because RFC 6455 section 5.5.2 clearly states that the only response to a ping is a pong with identical contents.

      Parameters:
        `data` - the data to write, may be at most 125 bytes
      Returns:
        a reference to this, so the API can be used fluently

          WebSocketBase writePong(Buffer data)

      Writes a pong to the connection. This will be written in a single frame. Pong 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 5.5.2.

      There is no need to manually write a Pong, as the server and client both handle responding to a ping with a pong automatically and this is exposed to users.RFC 6455 Section 5.5.3 states that pongs may be sent unsolicited in order to implement a one way heartbeat.

      Parameters:
        `data` - the data to write, may be at most 125 bytes
      Returns:
        a reference to this, so the API can be used fluently

    - #### closeHandler

          WebSocketBase closeHandler(Handler<Void> handler)

      Set a close handler. This will be called when the WebSocket is closed.

      After this callback, no more messages are expected.
      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### frameHandler

          WebSocketBase frameHandler(Handler<WebSocketFrame> handler)

      Set a frame handler on the connection. This handler will be called when frames are read on the connection.
      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### textMessageHandler

          WebSocketBase textMessageHandler(Handler<String> handler)

      Set a text message handler on the connection. This handler will be called similar to the , but the buffer will be converted to a String first
      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### binaryMessageHandler

          WebSocketBase binaryMessageHandler(Handler<Buffer> handler)

      Set a binary message handler on the connection. This handler serves a similar purpose to `handler(io.vertx.core.Handler<io.vertx.reactivex.core.buffer.Buffer>)` 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.isFinal()` to find the boundaries).
      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### pongHandler

          WebSocketBase pongHandler(Handler<Buffer> handler)

      Set a pong message handler on the connection. This handler will be invoked every time a pong message is received on the server, and can be used by both clients and servers since the RFC 6455 Sections 5.5.2 and 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 pings should immediately be responded to with a pong with identical content

      Pong frames may be received unsolicited.

      Parameters:
        `handler` - the handler
      Returns:
        a reference to this, so the API can be used fluently
