- All Implemented Interfaces:
- Cache, java.io.Serializable

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.
