Interface UncheckedFunction<T,R>

Type Parameters:

T - the type of the input to the function

All Superinterfaces:

java.util.function.Function<T,R>

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 UncheckedFunction<T,R>
extends java.util.function.Function<T,R>

Operations that throw RepositoryException cannot be used as lambdas without "unchecking" those exceptions.
