# WebSocketBase 

###
Companion object WebSocketBase

#### trait WebSocketBase extends ReadStream[Buffer] with WriteStream[Buffer]

Base WebSocket implementation.

It implements both and so it can be used with io.vertx.scala.core.streams.Pump to pump data with flow control.

1.  abstract def asJava: AnyRef
   Definition Classes
     WebSocketBase → WriteStream → ReadStream → StreamBase
2.  abstract def binaryHandlerID(): String

   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.

   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. * @return the binary handler id

3.  abstract def binaryMessageHandler(handler: Handler[Buffer]): WebSocketBase

   Set a binary message handler on the connection.

   Set a binary message handler on the connection. This handler serves a similar purpose to io.vertx.scala.core.http.WebSocketBase#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 io.vertx.scala.core.http.WebSocketFrame#isFinal to find the boundaries). * @param handler the handler

   returns

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

4.  abstract def close(statusCode: Short, reason: Option[String]): Unit
5.  abstract def close(statusCode: Short): Unit
6.  abstract def close(): Unit

   Close the WebSocket sending the default close frame.

   Close the WebSocket sending the default close frame.

   No more messages can be sent.

7.  abstract def closeHandler(handler: Handler[Unit]): WebSocketBase

   Set a close handler.

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

   After this callback, no more messages are expected. * @param handler the handler

   returns

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

8.  abstract def drainHandler(handler: Handler[Unit]): WebSocketBase

   Set a drain handler on the stream.

   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 io.vertx.scala.core.streams.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`. * @param handler the handler

   returns

13.  abstract def fetch(amount: Long): WebSocketBase

    Fetch the specified `amount` of elements.

    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. * @return a reference to this, so the API can be used fluently

    Set a frame handler on the connection. This handler will be called when frames are read on the connection. * @param handler the handler

    returns

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

15.  abstract def handler(handler: Handler[Buffer]): WebSocketBase

      the local address for this socket

18.  abstract def pause(): WebSocketBase

    Pause the `ReadStream`, it sets the buffer in `fetch` mode and clears the actual demand.

    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`. * @return a reference to this, so the API can be used fluently

19.  abstract def pongHandler(handler: Handler[Buffer]): WebSocketBase

    Set a pong message handler on the connection.

    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. * @param handler the handler

    returns

22.  abstract def setWriteQueueMaxSize(maxSize: Int): WebSocketBase

    Set the maximum size of the write queue to `maxSize`.

    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 io.vertx.scala.core.net.NetSocket, the number of io.vertx.scala.core.eventbus.Message for a io.vertx.scala.core.eventbus.MessageProducer, etc... * @param maxSize the max size of the write stream

23.  abstract def subProtocol(): String

    Returns the websocket sub protocol selected by the websocket handshake.

    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.

24.  abstract def textHandlerID(): String

    When a `Websocket` is created it automatically registers an event handler with the eventbus, the ID of that handler is given by `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.

25.  abstract def textMessageHandler(handler: Handler[String]): WebSocketBase

    Set a text message handler on the connection.

    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 * @param handler the handler

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

26.  abstract def write(data: Buffer): WebSocketBase

    Write some data to the stream.

    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 io.vertx.scala.core.streams.WriteStream#writeQueueFull method before writing. This is done automatically if using a io.vertx.scala.core.streams.Pump. * @param data the data to write

    Writes a (potentially large) piece of binary data to the connection. This data might be written as multiple frames if it exceeds the maximum WebSocket frame size. * @param data the data to write

    returns

31.  abstract def writePing(data: Buffer): WebSocketBase

    Writes a ping to the connection.

    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. * @param data the data to write, may be at most 125 bytes

    returns

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

32.  abstract def writePong(data: Buffer): WebSocketBase

    Writes a pong to the connection.

    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. * @param data the data to write, may be at most 125 bytes

    returns

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

33.  abstract def writeQueueFull(): Boolean
