Defines a callback method for notifying applications when an item is added to the Cache.
Namespace:
Assembly: Alachisoft.NCache.Web.dll
Syntax
[Obsolete("This delegate is deprecated. 'Please use CacheDataNotificationCallback(string key, CacheEventArg cacheEventArgs)'", false)]
public delegate void CacheItemAddedCallback(string key);Parameters
| Type | Name | Description |
|---|---|---|
| System.String | key | The cache key used to reference the item. |
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 CacheItemAddedCallback class to notify an application when an item is added to the application's Cache object. You could include this code in a code declaration block in the Web Forms page, or in a page code-behind file.
public void OnItemAdded(string k)
{
// ...
}
protected void Application_Start(object sender, EventArgs e)
{
try
{
NCache.InitializeCache("myCache");
NCache.Cache.ItemAdded += new CacheItemAddedCallback(this.OnItemAdded);
}
catch(Exception e)
{
}
}
