toOrderedList

public java.util.List<java.util.Set<E>> toOrderedList()

Returns elements as orderd list from most frequent to least frequent Elements of the list are Sets of E elements. Every element of the set was added the same number of times. Thus a CountingHashSet that recived three adds of an element t, two adds of element j and three adds of element k would return a list { set {t,k}, set{j}}

getCountMap

public java.util.HashMap<E,java.lang.Integer> getCountMap()
