ClientWebSocket pause()
```
    Description copied from interface: ReadStream
    
    Pause the ReadStream, it sets the buffer in fetch mode and clears the actual demand.
    While it's paused, no data will be sent to the data handler.
    
    Specified by:
    
    pause in interface ReadStream<Buffer>
    
    Specified by:
    
    pause in interface WebSocket
    
    Specified by:
    
    pause in interface WebSocketBase
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - resume
```
default ClientWebSocket resume()
```
    Description copied from interface: ReadStream
    
    Resume reading, and sets the buffer in flowing mode.
    If the ReadStream has been paused, reading will recommence on it.
    
    Specified by:
    
    resume in interface ReadStream<Buffer>
    
    Specified by:
    
    resume in interface WebSocket
    
    Specified by:
    
    resume in interface WebSocketBase
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - fetch
```
ClientWebSocket fetch(long amount)
```
    Description copied from interface: ReadStream
    
    Fetch the specified amount of elements. If the ReadStream has been paused, reading will recommence with the specified amount of items, otherwise the specified amount will be added to the current stream demand.
    
    Specified by:
    
    fetch in interface ReadStream<Buffer>
    
    Specified by:
    
    fetch in interface WebSocket
    
    Specified by:
    
    fetch in interface WebSocketBase
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - setWriteQueueMaxSize
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    setWriteQueueMaxSize in interface WebSocketBase
    
    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
  - handler
```
ClientWebSocket handler(Handler<Buffer> handler)
```
    Description copied from interface: ReadStream
    
    Set a data handler. As data is read, the handler will be called with the data.
    
    Specified by:
    
    handler in interface ReadStream<Buffer>
    
    Specified by:
    
    handler in interface WebSocket
    
    Specified by:
    
    handler in interface WebSocketBase
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - endHandler
```
ClientWebSocket endHandler(Handler<Void> endHandler)
```
    Description copied from interface: ReadStream
    
    Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.
    
    Specified by:
    
    endHandler in interface ReadStream<Buffer>
    
    Specified by:
    
    endHandler in interface WebSocket
    
    Specified by:
    
    endHandler in interface WebSocketBase
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - drainHandler
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    drainHandler in interface WebSocketBase
    
    Specified by:
    
    drainHandler in interface WriteStream<Buffer>
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - closeHandler
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    closeHandler in interface WebSocketBase
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - frameHandler
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    frameHandler in interface WebSocketBase
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - textMessageHandler
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    textMessageHandler in interface WebSocketBase
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - binaryMessageHandler
```
ClientWebSocket 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.isFinal() to find the boundaries).
    
    Specified by:
    
    binaryMessageHandler in interface WebSocket
    
    Specified by:
    
    binaryMessageHandler in interface WebSocketBase
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - pongHandler
```
ClientWebSocket 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 WebSocket
    
    Specified by:
    
    pongHandler in interface WebSocketBase
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - exceptionHandler
```
ClientWebSocket exceptionHandler(Handler<Throwable> handler)
```
    Description copied from interface: ReadStream
    
    Set an exception handler on the read stream.
    
    Specified by:
    
    exceptionHandler in interface ReadStream<Buffer>
    
    Specified by:
    
    exceptionHandler in interface StreamBase
    
    Specified by:
    
    exceptionHandler in interface WebSocket
    
    Specified by:
    
    exceptionHandler in interface WebSocketBase
    
    Specified by:
    
    exceptionHandler in interface WriteStream<Buffer>
    
    Parameters:
    
    handler - the exception handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
