Class WcmMRUCollection
java.lang.Object
com.filenet.wcm.toolkit.util.WcmMRUCollection
- All Implemented Interfaces:
- java.util.Collection
- public class WcmMRUCollection
- extends java.lang.Object
- implements java.util.Collection
This class provides a limited amount of "most recently used" storage,
with a pre-defined limit on how many items can be stored.
When you add a new item, if you're at the limit, then the least recently used
item gets thrown away to make space for the new one, which is added to the top
of the list.
This class implements Collection interface, which means the only way to access
the elements is using iterator() method. This is simular to Sets, but there are
no constrains on the objects that can be stored. When iterating through the elements,
elements returned by Iterator.next() method are not moved to the top of the list.
