Interface PermutationFullUnaryOperator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface PermutationFullUnaryOperator

A functional interface for defining custom unary operators on Permutations. See the Permutation.apply(PermutationFullUnaryOperator) method. In this interface, the apply(int[], org.cicirello.permutations.Permutation) method is passed both a reference to the raw array of ints that is encapsulated by the Permutation, as well as a reference to the Permutation object itself to enable utilizing the methods of the Permutation class. If the operator that you are implementing only requires the raw array of ints, then consider implementing the PermutationUnaryOperator interface instead.

Method Summary

Modifier and Type	Method	Description
void	apply(int[] rawPermutation, Permutation p)	Applies an operator on the raw representation of a Permutation.

Method Details

apply

void apply(int[] rawPermutation,
 Permutation p)

Applies an operator on the raw representation of a Permutation. Implementers of this interface are responsible for ensuring that the apply method maintains a valid permutation of the integers in {0, 1, ..., rawPermutation.length - 1 }.

Parameters:

rawPermutation - A reference to the raw array of ints underlying a Permutation object. Changes to this array will directly change the Permutation object that encapsulates it.

p - A reference to the Permutation object that encapsulates it.
