Package io.vertx.rxjava3.ext.web.handler.sockjs

## Class SockJSSocket

- java.lang.Object
- - io.vertx.rxjava3.ext.web.handler.sockjs.SockJSSocket

- All Implemented Interfaces:
    `io.vertx.lang.rx.RxDelegate`, `ReadStream<Buffer>`, `StreamBase`, `WriteStream<Buffer>`

      public class SockJSSocket
      extends Object
      implements io.vertx.lang.rx.RxDelegate, ReadStream<Buffer>, WriteStream<Buffer>

  You interact with SockJS clients through instances of SockJS socket.

  The API is very similar to `WebSocket`. It implements both and so it can be used with 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

          public Completable write​(Buffer data)

      Description copied from interface: `WriteStream`
      Write some data to the stream.

      The data is usually 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 `Pipe`.

      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.

      Specified by:
        `write` in interface `WriteStream<Buffer>`
      Parameters:
        `data` - the data to write
      Returns:
        a future completed with the write result

    - #### rxWrite

          public Completable rxWrite​(Buffer data)

      Description copied from interface: `WriteStream`

      The data is usually 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 `Pipe`.

      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.

    - #### rxWrite

          public Completable rxWrite​(String data)

      Parameters:
        `data` - the string to write
      Returns:

    - #### setWriteQueueMaxSize

          public SockJSSocket 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 `WriteStream<Buffer>`
      Parameters:
        `maxSize` - the max size of the write stream
      Returns:
        a reference to this, so the API can be used fluently

    - #### drainHandler

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

    - #### writeHandlerID

          public String writeHandlerID()

      When a `SockJSSocket` is created it can register an event handler with the event bus, the ID of that handler is given by `writeHandlerID`.

      Given this ID, a different event loop can send a buffer 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 socket. This allows you to write data to other sockets which are owned by different event loops.

      Returns:
        the `writeHandlerID` or `null` if `writeHandler` registration is disabled in `SockJSHandlerOptions`
