Methods

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.

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.

Source:
Returns:
the binary handler id
Type
string

binaryMessageHandler(handler) → {WebSocketBase}

Set a binary message handler on the connection. This handler serves a similar purpose to WebSocket#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).
Parameters:
Name Type Description
handler function the handler
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

close()

Close the WebSocket.
Source:

closeHandler(handler) → {WebSocket}

Parameters:
Name Type Description
handler function
Source:
Returns:
Type
WebSocket

drainHandler(handler) → {WebSocket}

Parameters:
Name Type Description
handler function
Source:
Returns:
Type
WebSocket

end(t)

Same as WebSocketBase#end but writes some data to the stream before ending.
Parameters:
Name Type Description
t Buffer
Source:

endHandler(endHandler) → {WebSocket}

Parameters:
Name Type Description
endHandler function
Source:
Returns:
Type
WebSocket

exceptionHandler(handler) → {WebSocket}

Parameters:
Name Type Description
handler function
Source:
Returns:
Type
WebSocket

frameHandler(handler) → {WebSocket}

Parameters:
Name Type Description
handler function
Source:
Returns:
Type
WebSocket

handler(handler) → {WebSocket}

Parameters:
Name Type Description
handler function
Source:
Returns:
Type
WebSocket

isSsl() → {boolean}

Source:
Returns:
true if this HttpConnection is encrypted via SSL/TLS.
Type
boolean

localAddress() → {SocketAddress}

Source:
Returns:
the local address for this socket
Type
SocketAddress

pause() → {WebSocket}

Source:
Returns:
Type
WebSocket

remoteAddress() → {SocketAddress}

Source:
Returns:
the remote address for this socket
Type
SocketAddress

resume() → {WebSocket}

Source:
Returns:
Type
WebSocket

setWriteQueueMaxSize(maxSize) → {WebSocket}

Parameters:
Name Type Description
maxSize number
Source:
Returns:
Type
WebSocket

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.

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.

Source:
Returns:
Type
string

textMessageHandler(handler) → {WebSocketBase}

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
Parameters:
Name Type Description
handler function the handler
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

write(data) → {WebSocket}

Parameters:
Name Type Description

writeQueueFull() → {boolean}

Source:
Returns:
true if write queue is full
Type
boolean
