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 CacheClearedCallback()
Visual Basic
Public Delegate Sub CacheClearedCallback
Visual C++
public delegate void CacheClearedCallback()

Remarks

Since this handler is invoked every time the Cache is cleared, 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 CacheClearedCallback class to notifiy an application when the application's Cache object is cleared. You could include this code in a code declaration block in the Web Forms page, or in a page code-behind file.

public void OnCacheCleared()
{
    // ...
}

protected void Application_Start(object sender, EventArgs e)
{
    try
    {
        NCache.InitializeCache("myCache");
        NCache.Cache.CacheCleared += new CacheClearedCallback(this.OnCacheCleared);
    }
    catch(Exception e)
    {
    }
}
