java.lang.Object

org.aksw.palmetto.prob.decorator.AbstractFrequencyDeterminerDecorator

org.aksw.palmetto.prob.decorator.AbstractSlidingWindowFrequencyDeterminerDecorator

All Implemented Interfaces:

FrequencyDeterminerDecorator, SlidingWindowFrequencyDeterminerDecorator, FrequencyDeterminer, WindowBasedFrequencyDeterminer

public class SimpleFrequencyCachingDeterminerDecorator
extends AbstractSlidingWindowFrequencyDeterminerDecorator

This decorator implements a very simple cache. Note that it has disadvantages, e.g., it will never stop growing. Thus, the FrequencyCachingDeterminerDecorator should be used instead.
