Enum CacheItemPriority

Specifies the relative priority of items stored in the Cache.

Namespace:

Assembly: Alachisoft.NCache.Runtime.dll

Syntax

[Serializable]
public enum CacheItemPriority : byte

Remarks

When the application's cache is full or runs low on memory, the Cache selectively purges items to free system memory. When an item is added to the Cache, you can assign it a relative priority compared to the other items stored in the Cache.

Items you assign higher priority values to are less likely to be deleted from the Cache when the server is processing a large number of requests, while items you assign lower priority values are more likely to be deleted. The default is Normal.

Examples

The following example demonstrates how to set CacheItemPriority of an item in a Cache to High.

CacheItem item = new CacheItem(product);
item.Priority = CacheItemPriority.High;

Name	Description
AboveNormal	Cache items with this priority level are less likely to be deleted as the server frees system memory than those assigned a Normal priority.
BelowNormal	Cache items with this priority level are more likely to be deleted from the cache as the server frees system memory than items assigned a Normal priority.
Default	The default value for a cached item's priority is Normal.
CacheItemPriority	Cache items with this priority level are the least likely to be deleted from the cache as the server frees system memory.
Low	Cache items with this priority level are the most likely to be deleted from the cache as the server frees system memory.
CacheItemPriority	Cache items with this priority level are likely to be deleted from the cache as the server frees system memory only after those items with Low or BelowNormal priority. This is the default.
NotRemovable	The cache items with this priority level will not be deleted from the cache as the server frees system memory.
