public final class PatternCacheFIFO2 extends GenericPatternCache
This class is a GenericPatternCache subclass implementing a second chance 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, when a new pattern is added to the cache, it replaces the first of the current patterns in the cache to have been added, unless that pattern has been used recently (generally between the last cache replacement and now). If the pattern to be replaced has been used, it is given a second chance, and the next pattern in the cache is tested for replacement in the same manner. If all the patterns are given a second chance, then the original pattern selected for replacement is replaced.
