Interface I_CmsLruCacheObject

All Known Implementing Classes:

CmsFlexCacheEntry

public interface I_CmsLruCacheObject

Defines the methods which an object being cached by CmsFlexLruCache must implement.

CmsFlexLruCache is organized as a double linked list, that's why objects implementing this interface need getters/setter for the next/previous nodes in the list of all cached objects.
