- - ### Method Detail

    - #### getSendTimeout

          long getSendTimeout()

      Obtain the timeout (in milliseconds) for sending a message asynchronously. The default value is determined by `WebSocketContainer.getDefaultAsyncSendTimeout()`.
      Returns:
        The current send timeout in milliseconds. A non-positive value means an infinite timeout.

    - #### setSendTimeout

          void setSendTimeout(long timeout)

      Set the timeout (in milliseconds) for sending a message asynchronously. The default value is determined by `WebSocketContainer.getDefaultAsyncSendTimeout()`.
      Parameters:
        `timeout` - The new timeout for sending messages asynchronously in milliseconds. A non-positive value means an infinite timeout.

    - #### sendText

          void sendText(java.lang.String text,
                      SendHandler completion)

      Send the message asynchronously, using the SendHandler to signal to the client when the message has been sent.
      Parameters:
        `text` - The text message to send
        `completion` - Used to signal to the client when the message has been sent

    - #### sendText

          java.util.concurrent.Future<java.lang.Void> sendText(java.lang.String text)

      Send the message asynchronously, using the Future to signal to the client when the message has been sent.
      Parameters:
        `text` - The text message to send
      Returns:
        A Future that signals when the message has been sent.

    - #### sendBinary

          java.util.concurrent.Future<java.lang.Void> sendBinary(java.nio.ByteBuffer data)

      Send the message asynchronously, using the Future to signal to the client when the message has been sent.
      Parameters:
        `data` - The text message to send
      Returns:
        A Future that signals when the message has been sent.
      Throws:
        `java.lang.IllegalArgumentException` - if `data` is `null`.

    - #### sendBinary

          void sendBinary(java.nio.ByteBuffer data,
                        SendHandler completion)

      Send the message asynchronously, using the SendHandler to signal to the client when the message has been sent.
      Parameters:
        `data` - The text message to send
        `completion` - Used to signal to the client when the message has been sent
      Throws:
        `java.lang.IllegalArgumentException` - if `data` or `completion` is `null`.

    - #### sendObject

          java.util.concurrent.Future<java.lang.Void> sendObject(java.lang.Object obj)

      Encodes object as a message and sends it asynchronously, using the Future to signal to the client when the message has been sent.
      Parameters:
        `obj` - The object to be sent.
      Returns:
        A Future that signals when the message has been sent.
      Throws:
        `java.lang.IllegalArgumentException` - if `obj` is `null`.

    - #### sendObject

          void sendObject(java.lang.Object obj,
                        SendHandler completion)

      Encodes object as a message and sends it asynchronously, using the SendHandler to signal to the client when the message has been sent.
      Parameters:
        `obj` - The object to be sent.
        `completion` - Used to signal to the client when the message has been sent
      Throws:
        `java.lang.IllegalArgumentException` - if `obj` or `completion` is `null`.
