Interface AddToIntSet

All Superinterfaces:

AddToSet<Integer>

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 AddToIntSet
extends AddToSet<Integer>

Represents a function that adds an element to a set if not already present.

The set can be implemented in various ways. For example:

• The set can be an implementation of one of the collection classes provided by the Java API.

           AddToIntSet=new HashSet<Integer>()::add;
           

• The set can be a marker bit in a BitSet.

          AddToIntSet=AddToIntSet.addToBitSet(new BitSet());
