Interface I_CmsFlexLruCacheObject

All Known Implementing Classes:: CmsLruHashMap.CmsLruCacheObject

public interface I_CmsFlexLruCacheObject

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.

Version:: $Revision: 1.4 $

Method Summary

void addToLruCache()
          Invoked after an object was added to the cache.

int getLruCacheCosts()
          Returns the cache costs of this object, as for example it's byte size.

I_CmsFlexLruCacheObject getNextLruObject()
          Returns the next object in the double linked list of all cached objects.

I_CmsFlexLruCacheObject getPreviousLruObject()
          Returns the previous object in the double linked list of all cached objects.

void removeFromLruCache()
          Invoked after the object was removed to the cache.

void setNextLruObject(I_CmsFlexLruCacheObject theNextObject)
          Set the next object in the double linked list of all cached objects.

void setPreviousLruObject(I_CmsFlexLruCacheObject thePreviousObject)
          Set the previous object in the double linked list of all cached objects.
