Defines a callback method for notifying applications when a request for asynchronous cache clear operation completes.

Namespace: Alachisoft.NCache.Web.Caching
Assembly: Alachisoft.NCache.Web (in Alachisoft.NCache.Web.dll) Version: 4.3.0.0 (4.3.0.0)

Syntax

C#
public delegate void AsyncCacheClearedCallback(
	Object result
)
Visual Basic
Public Delegate Sub AsyncCacheClearedCallback ( 
	result As Object
)
Visual C++
public delegate void AsyncCacheClearedCallback(
	Object^ result
)

Parameters

result
Type: System..::..Object
The result of the asynchronous operation. If the operation completes successfully, it contains Success otherwise it contains an OperationFailedException indicating the cause of the operation failure.

Remarks

Since this handler is invoked every time an item is removed from the Cache, doing a lot of processing inside the handler might have an impact on the performance of the cache and cluster. It is therefore advisable to do minimal processing inside the handler.

Examples

The following example demonstrates how to use the AsyncCacheClearedCallback class to notifiy an application when application's Cache object is cleared asynchronously. You could include this code in a code declaration block in the Web Forms page, or in a page code-behind file.

public void OnAsyncCacheCleared(object result)
{
    // ...
}

protected void Application_Start(object sender, EventArgs e)
{
    try
    {
        NCache.InitializeCache("myCache");
        NCache.Cache.ClearAsync(new AsyncCacheClearedCallback(OnAsyncCacheCleared));
    }
    catch(Exception e)
    {
    }
}
