org.apache.oro.util.CacheFIFO

所有已实现的接口:

Serializable, Cache

public final class CacheFIFO
extends GenericCache

This class is a GenericCache subclass implementing a 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, if a new pattern is added to the cache, it replaces the first of the current patterns in the cache to have been added.
