Class PatternCacheLRU
- PatternCache
public final class PatternCacheLRU
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.

PatternCacheLRU() - Same as:
PatternCacheLRU(GenericPatternCache.DEFAULT_CAPACITY);

PatternCacheLRU(int capacity) - Same as:
PatternCacheLRU(capacity, new Perl5Compiler());

PatternCacheLRU(int capacity, PatternCompiler compiler) - Creates a PatternCacheLRU instance with a given cache capacity,
and initialized to use a given PatternCompiler instance as a pattern
compiler.

PatternCacheLRU(PatternCompiler compiler) - Same as:
PatternCacheLRU(GenericPatternCache.DEFAULT_CAPACITY, compiler);

public PatternCacheLRU(int capacity,
PatternCompiler compiler)
Creates a PatternCacheLRU instance with a given cache capacity,
and initialized to use a given PatternCompiler instance as a pattern
compiler.
capacity
- The capacity of the cache.compiler
- The PatternCompiler to use to compile patterns.
