Method Detail

getWeight

public abstract java.lang.Comparable getWeight(T t,
                                               ProcessingContext context)

classify

public java.lang.Iterable<T> classify(java.lang.Iterable<? extends T> source,
                                      ProcessingContext context)

Specified by:

classify in class Classifier<T>

getSortingWeights

public java.util.List<Pair<T,java.lang.Object>> getSortingWeights(java.lang.Iterable<? extends T> items,
                                                                  ProcessingContext context)

Specified by:

getSortingWeights in class Classifier<T>

Returns:

a mapping from the given items to objects (e.g. Comparable instances) used to sort the items in Classifier.classify(Iterable, ProcessingContext). May return an empty list if there are no suitable objects available. Used for diagnostics and statistic collection.
