Method Details

ambiguityReducing

public static final <C,E> Selectable<C,E> ambiguityReducing(Selectable<C,E> s,
 Predicate<? super E> p,
 ToIntFunction<? super E> rankingFunction)

Returns a Selectable that reduces any ambiguity in the results returned by another Selectable, considering notional alternate status and rank.

Type Parameters:

C - the criteria type

E - the element type

Parameters:

s - a Selectable; must not be null

p - a Predicate that tests whether an element is an alternate; may be null in which case it will be as if e -> false were supplied

rankingFunction - a ToIntFunction that returns a rank for an alternate; a rank of 0 indicates no particular rank; may be null in which case it will be as if e -> 0 were supplied

Returns:

a non-null Selectable

Throws:

NullPointerException - if any argument is null
