- public final class PatternCacheLRU
- extends GenericPatternCache
This class is a GenericPatternCache subclass implementing an LRU
(Least Recently Used) cache replacement policy. In other words,
patterns are added to the cache until it becomes full. Once the
cache is full, when a new pattern is added to the cache, it replaces
the least recently used pattern currently in the cache. This is probably
the best general purpose pattern cache replacement policy.
