All Implemented Interfaces:
PatternCache

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.
