Package Samples:

• org.apache.oro.util

Classes:

• CacheFIFO2: This class is a GenericCache subclass implementing a second chance FIFO (First In First Out) cache replacement policy. In other words, values are added to the cache until the cache becomes full. Once the cache is full, when a new value is added to the cache, it replaces the first of the current values in the cache to have been added, unless that value has been used recently (generally between the last cache replacement and now). If the value to be replaced has been used, it is given a second chance, and the next value in the cache is tested for replacement in the same manner. If all the values ...
• GenericCache: This is the base class for all cache implementations provided in the org.apache.oro.util package. To derive a subclass from GenericCache only the ... methods need be overridden. Although 4 subclasses of GenericCache are provided with this package, users may not derive subclasses from this class. Rather, users should create their own implmentations of the Cache interface.
• CacheLRU: This class is a GenericCache subclass implementing an LRU (Least Recently Used) cache replacement policy. In other words, values are added to the cache until it becomes full. Once the cache is full, when a new value is added to the cache, it replaces the least recently used value currently in the cache. This is probably the best general purpose cache replacement policy.
• CacheFIFO: This class is a GenericCache subclass implementing a FIFO (First In First Out) cache replacement policy. In other words, values 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.
• CacheRandom: This class is a GenericCache subclass implementing a random cache replacement policy. In other words, values are added to the cache until it becomes full. Once the cache is full, when a new value is added to the cache, it replaces a randomly selected value in the cache.
• GenericCacheEntry: A structure used to store values in a GenericCache. It is declared with default access to limit it to use only within the package.
• Cache: An interface defining the basic functions of a cache.
