Asynchronous request to change the watched alert filters.

Namespace: ININ.IceLib.Statistics.Alerts
Assembly: ININ.IceLib.Statistics (in ININ.IceLib.Statistics.dll) Version: 0.0.0.0 (22.3.0.218)

Syntax

C#
public void ChangeWatchedAlertsAsync(
	AlertFilterKey[] keysToAdd,
	AlertFilterKey[] keysToRemove,
	bool replaceExisting,
	AlertListenerFilter filter,
	AsyncCompletedEventHandler completedCallback,
	Object userState
)
Visual Basic
Public Sub ChangeWatchedAlertsAsync ( _
	keysToAdd As AlertFilterKey(), _
	keysToRemove As AlertFilterKey(), _
	replaceExisting As Boolean, _
	filter As AlertListenerFilter, _
	completedCallback As AsyncCompletedEventHandler, _
	userState As Object _
)

Parameters

keysToAdd
Type: array<ININ.IceLib.Statistics.Alerts..::..AlertFilterKey>[]()[][]
The keys of the alert filters to add. (Can be nullNothingnullptra null reference (Nothing in Visual Basic).)
keysToRemove
Type: array<ININ.IceLib.Statistics.Alerts..::..AlertFilterKey>[]()[][]
The keys of the alert filters to remove. (Can be nullNothingnullptra null reference (Nothing in Visual Basic).)
replaceExisting
Type: System..::..Boolean
if set to trueTruetruetrue (True in Visual Basic), replace the existing list.
filter
Type: ININ.IceLib.Statistics.Alerts..::..AlertListenerFilter
The filter to apply to the AlertChanged event.
completedCallback
Type: System.ComponentModel..::..AsyncCompletedEventHandler
The callback to invoke when the asynchronous operation completes.
userState
Type: System..::..Object
An optional object that contains state information for this request. This object is a way for the caller to store context information which will be provided to the AsyncCompleted event. If no context information is desired then nullNothingnullptra null reference (Nothing in Visual Basic) may be supplied.

Remarks

When completed, the completedCallback delegate is invoked on a thread appropriate to the application-model, such as the GUI thread in a UI application. The Error property of the AsyncCompletedEventArgs-derived object passed to the delegate will contain any exceptions thrown while executing the asynchronous task. See the synchronous version of this method for more detailed error information. For more information on async method calls, see How Async Calls Work.

Note
For more information on watches see How Watches Work.

Exceptions

ExceptionCondition
System..::..InvalidOperationExceptionThis AlertListener is not watched.
