All Implemented Interfaces:

PatternCache

public final class PatternCacheFIFO

extends GenericPatternCache

This class is a GenericPatternCache subclass implementing a FIFO (First In First Out) cache replacement policy. In other words, patterns 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.
