Delegate AsyncCacheClearedCallback

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

Namespace:

Assembly: Alachisoft.NCache.Web.dll

Syntax

public delegate void AsyncCacheClearedCallback(object result);

Parameters

Type	Name	Description
System.Object	result	The result of the asynchronous operation. If the operation completes successfully, it contains Alachisoft.NCache.Caching.AsyncOpResult.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)
    {
    }
}
