所有已实现的接口:
Serializable, Cache
public final class CacheFIFO2 extends GenericCache
This class is a GenericCache subclass implementing a second chance FIFO (First In First Out) cache replacement policy. In other words, values are added to the cache until the cache becomes full. Once the cache is full, when a new value is added to the cache, it replaces the first of the current values in the cache to have been added, unless that value has been used recently (generally between the last cache replacement and now). If the value to be replaced has been used, it is given a second chance, and the next value in the cache is tested for replacement in the same manner. If all the values are given a second chance, then the original pattern selected for replacement is replaced.

    • addElement

      public final void addElement(Object key, Object value)
      Adds a value to the cache. If the cache is full, when a new value is added to the cache, it replaces the first of the current values in the cache to have been added (i.e., FIFO2).
