Interface ThrowableUnaryOperator<T>

  • Type Parameters:
    T - the type of the operand and result of the operator
    All Superinterfaces:
    java.util.function.Function<T,​T>, ThrowableFunction<T,​T>
    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 ThrowableUnaryOperator<T>
extends ThrowableFunction<T,​T>
    Represents an operation on a single operand that produces a result of the same type as its operand. This is a specialization of Function for the case where the operand and result are of the same type.

    Permits checked exceptions unlike UnaryOperator

    This is a functional interface whose functional method is ThrowableFunction.apply(Object).
