Method Detail

addElement

public void addElement(T t,
                       ProcessingContext context)

classify

getSortingWeights

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

Returns:

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

getNext
