Interface MapImmutableSetter<M,K,V>

Type Parameters:

M - the generic type of the model.

All Superinterfaces:

java.util.function.BiFunction<M,Map<K,V>,M>

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 MapImmutableSetter<M,K,V>
extends java.util.function.BiFunction<M,Map<K,V>,M>

A functional interface to define an immutable "setter" method of type Map. As the model element is immutable this method is not a real "setter". Instead it returns a new immutable copy of the original model element that has the specified field updated to the new value.
