WebSocketProxyConnectionTimeout Property

This property specifies a timeout for the class.

Syntax

 websocketproxy.getWebSocketProxyConnectionTimeout(index, [callback])
 websocketproxy.setWebSocketProxyConnectionTimeout(index,  webSocketProxyConnectionTimeout, [callback])

Default Value

0

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getWebSocketProxyConnectionTimeout([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setWebSocketProxyConnectionTimeout([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property specifies a timeout for the class.

If the WebSocketProxyConnectionTimeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If WebSocketProxyConnectionTimeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of WebSocketProxyConnectionTimeout seconds.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the WebSocketProxyConnectionTimeout property is 0 (asynchronous operation).

The size of the array is controlled by the WebSocketProxyConnectionCount property.

This property is not available at design time.
