所有已实现的接口:

PatternCache

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.

public PatternCacheFIFO2(int capacity,
                         PatternCompiler compiler)

Creates a PatternCacheFIFO2 instance with a given cache capacity, initialized to use a given PatternCompiler instance as a pattern compiler.

参数:

capacity - The capacity of the cache.

compiler - The PatternCompiler to use to compile patterns.
