Constructor Summary
public  UnlimitedCache()
     Creates an unlimited cache by calling the super class's constructor with an UNLIMITED maximum number of entries.

Method Summary
protected  voiditemPut(Object key)
     Implements itemPut with an empty implementation.
protected  voiditemRemoved(Object key)
     An empty implementation.
protected  voiditemRetrieved(Object key)
     Implements itemRetrieved with an empty implementation.
protected  ObjectremoveItem()
    
public  voidsetMaxEntries(int maxEntries)
     Overrides the setMaxEntries with an empty implementation.


Constructor Detail
UnlimitedCache
public UnlimitedCache()(Code)
Creates an unlimited cache by calling the super class's constructor with an UNLIMITED maximum number of entries.



Method Detail
itemPut
protected void itemPut(Object key)(Code)
Implements itemPut with an empty implementation. The unlimited cache doesn't care that an item was put in the cache.


itemRemoved
protected void itemRemoved(Object key)(Code)
An empty implementation. The unlimited cache doesn't care that an item was removed.


itemRetrieved
protected void itemRetrieved(Object key)(Code)
Implements itemRetrieved with an empty implementation. The unlimited cache doesn't care that an item was retrieved.


removeItem
protected Object removeItem()(Code)
This method just returns null since items should never end up being removed from an unlimited cache!


setMaxEntries
public void setMaxEntries(int maxEntries)(Code)
Overrides the setMaxEntries with an empty implementation. This property cannot be modified and is ignored for an UnlimitedCache.
