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

close()

Close the WebSocket.
Source:

closeHandler(handler) → {WebSocketBase}

Set a close handler. This will be called when the WebSocket is closed.
Parameters:
Name Type Description
handler function the handler
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

drainHandler(handler) → {WebSocketBase}

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

endHandler(endHandler) → {WebSocketBase}

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

exceptionHandler(handler) → {WebSocketBase}

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

frameHandler(handler) → {WebSocketBase}

Set a frame handler on the connection. This handler will be called when frames are read on the connection.
Parameters:
Name Type Description
handler function the handler
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

handler(handler) → {WebSocketBase}

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

localAddress() → {SocketAddress}

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

pause() → {WebSocketBase}

Source:
Returns:
Type
WebSocketBase

remoteAddress() → {SocketAddress}

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

resume() → {WebSocketBase}

Source:
Returns:
Type
WebSocketBase

setWriteQueueMaxSize(maxSize) → {WebSocketBase}

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

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

write(data) → {WebSocketBase}

Parameters:
Name Type Description
data Buffer
Source:
Returns:
Type
WebSocketBase

writeFrame(frame) → {WebSocketBase}

Write a WebSocket frame to the connection
Parameters:
Name Type Description
frame WebSocketFrame the frame to write
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

writeMessage(data) → {WebSocketBase}

Writes a (potentially large) piece of data to the connection. This data might be written as multiple frames if it exceeds the maximum WebSocket frame size.
Parameters:
Name Type Description
data Buffer the data to write
Source:
Returns:
a reference to this, so the API can be used fluently
Type
WebSocketBase

writeQueueFull() → {boolean}

This will return true if there are more bytes in the write queue than the value set using WebSocketBase#setWriteQueueMaxSize
Source:
Returns:
true if write queue is full
Type
boolean
