Method Detail
-
connect
Future<WebSocket> connect(WebSocketConnectOptions options)
Connect this WebSocket with the specified options.- Parameters:
options- the request options- Returns:
- a future notified when the WebSocket when connected
-
connect
default Future<WebSocket> connect(int port, String host, String requestURI)
Connect this WebSocket to the specified port, host and relative request URI.- Parameters:
port- the porthost- the hostrequestURI- the relative URI- Returns:
- a future notified when the WebSocket when connected
-
connect
default Future<WebSocket> connect(String host, String requestURI)
Connect this WebSocket to the host and relative request URI and default port.- Parameters:
host- the hostrequestURI- the relative URI- Returns:
- a future notified when the WebSocket when connected
-
connect
default Future<WebSocket> connect(String requestURI)
Connect this WebSocket at the relative request URI using the default host and port.- Parameters:
requestURI- the relative URI- Returns:
- a future notified when the WebSocket when connected
-
pause
ClientWebSocket pause()
Description copied from interface:ReadStreamPause theReadStream, it sets the buffer infetchmode and clears the actual demand.While it's paused, no data will be sent to the data
handler.- Specified by:
pausein interfaceReadStream<Buffer>- Specified by:
pausein interfaceWebSocket- Specified by:
pausein interfaceWebSocketBase- Returns:
- a reference to this, so the API can be used fluently
-
resume
default ClientWebSocket resume()
Description copied from interface:ReadStreamResume reading, and sets the buffer inflowingmode. If theReadStreamhas been paused, reading will recommence on it.- Specified by:
resumein interfaceReadStream<Buffer>- Specified by:
resumein interfaceWebSocket- Specified by:
resumein interfaceWebSocketBase- Returns:
- a reference to this, so the API can be used fluently
-
fetch
ClientWebSocket fetch(long amount)
Description copied from interface:ReadStreamFetch the specifiedamountof elements. If theReadStreamhas been paused, reading will recommence with the specifiedamountof items, otherwise the specifiedamountwill be added to the current stream demand.- Specified by:
fetchin interfaceReadStream<Buffer>- Specified by:
fetchin interfaceWebSocket- Specified by:
fetchin interfaceWebSocketBase- Returns:
- a reference to this, so the API can be used fluently
-
setWriteQueueMaxSize
ClientWebSocket setWriteQueueMaxSize(int maxSize)
Description copied from interface:WriteStreamSet the maximum size of the write queue tomaxSize. You will still be able to write to the stream even if there is more thanmaxSizeitems in the write queue. This is used as an indicator by classes such asPipeto provide flow control. The value is defined by the implementation of the stream, e.g in bytes for aNetSocket, etc...- Specified by:
setWriteQueueMaxSizein interfaceWebSocket- Specified by:
setWriteQueueMaxSizein interfaceWebSocketBase- Specified by:
setWriteQueueMaxSizein interfaceWriteStream<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:ReadStreamSet a data handler. As data is read, the handler will be called with the data.- Specified by:
handlerin interfaceReadStream<Buffer>- Specified by:
handlerin interfaceWebSocket- Specified by:
handlerin interfaceWebSocketBase- Returns:
- a reference to this, so the API can be used fluently
-
endHandler
ClientWebSocket endHandler(Handler<Void> endHandler)
Description copied from interface:ReadStreamSet an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.- Specified by:
endHandlerin interfaceReadStream<Buffer>- Specified by:
endHandlerin interfaceWebSocket- Specified by:
endHandlerin interfaceWebSocketBase- Returns:
- a reference to this, so the API can be used fluently
-
drainHandler
ClientWebSocket drainHandler(Handler<Void> handler)
Description copied from interface:WriteStreamSet 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. SeePipefor 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:
drainHandlerin interfaceWebSocket- Specified by:
drainHandlerin interfaceWebSocketBase- Specified by:
drainHandlerin interfaceWriteStream<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:WebSocketBaseSet 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, theWebSocketBase.closeStatusCode()will return the status code andWebSocketBase.closeReason()will return the reason.- Specified by:
closeHandlerin interfaceWebSocket- Specified by:
closeHandlerin interfaceWebSocketBase- 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:WebSocketBaseSet a frame handler on the connection. This handler will be called when frames are read on the connection.- Specified by:
frameHandlerin interfaceWebSocket- Specified by:
frameHandlerin interfaceWebSocketBase- 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:WebSocketBaseSet a text message handler on the connection. This handler will be called similar to theWebSocketBase.binaryMessageHandler(Handler), but the buffer will be converted to a String first- Specified by:
textMessageHandlerin interfaceWebSocket- Specified by:
textMessageHandlerin interfaceWebSocketBase- 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:WebSocketBaseSet a binary message handler on the connection. This handler serves a similar purpose toWebSocketBase.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 (usingWebSocketFrame.isFinal()to find the boundaries).- Specified by:
binaryMessageHandlerin interfaceWebSocket- Specified by:
binaryMessageHandlerin interfaceWebSocketBase- 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:WebSocketBaseSet 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:
pongHandlerin interfaceWebSocket- Specified by:
pongHandlerin interfaceWebSocketBase- 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:ReadStreamSet an exception handler on the read stream.- Specified by:
exceptionHandlerin interfaceReadStream<Buffer>- Specified by:
exceptionHandlerin interfaceStreamBase- Specified by:
exceptionHandlerin interfaceWebSocket- Specified by:
exceptionHandlerin interfaceWebSocketBase- Specified by:
exceptionHandlerin interfaceWriteStream<Buffer>- Parameters:
handler- the exception handler- Returns:
- a reference to this, so the API can be used fluently
