Examples of MutableRecommendedItem

net.myrrix.common.MutableRecommendedItem
An implementation of {@link RecommendedItem} which is mutable. This lets implementationsreuse one object during its iterations rather than create new objects for each element. @author Sean Owen @since 1.0
org.apache.mahout.cf.taste.hadoop.MutableRecommendedItem
Mutable variant of {@link RecommendedItem}
