Classes in org.apache.mahout.cf.taste.impl.common used by org.apache.mahout.cf.taste.hadoop.item

Class and Description
FastIDSet

Classes in org.apache.mahout.cf.taste.impl.common used by org.apache.mahout.cf.taste.impl.common

Class and Description
AbstractLongPrimitiveIterator
Cache.MatchPredicate Used by {#link #removeKeysMatching(Object)} to decide things that are matching.
FastByIDMap
FastIDSet
FastMap This is an optimized Map implementation, based on algorithms described in Knuth's "Art of Computer Programming", Vol.
FixedRunningAverage A simple class that represents a fixed value of an average and count.
FullRunningAverage A simple class that can keep track of a running average of a series of numbers.
LongPrimitiveIterator Adds notion of iterating over long primitives in the style of an Iterator -- as opposed to iterating over Long.
Retriever Implementations can retrieve a value for a given key.
RunningAverage Interface for classes that can keep track of a running average of a series of numbers.
RunningAverageAndStdDev Extends RunningAverage by adding standard deviation too.
SkippingIterator Adds ability to skip ahead in an iterator, perhaps more efficiently than by calling Iterator.next() repeatedly.
