Interface KeyUtils.SourceKeysFunction<T,R>

Type Parameters:
T - the type of the first argument to the function.
R - the type of the result of the function.
Enclosing class:
KeyUtils
public static interface KeyUtils.SourceKeysFunction<T,R>
Represents a function that accepts two arguments of the same base type and produces a result while the second argument is an array of T. This is similar to a BiFunction but restricts both arguments to be of the same type. Typically used in arrangements where a composite collection of keys is split into the first key and the remaining keys.

This is a functional interface whose functional method is apply(Object, Object[]).
