Interface UnaryOperatorEx<T,E extends java.lang.Throwable>

Type Parameters:

T - the type of the operand and result of the operator

E - the type of exception could be thrown while performing operation

All Superinterfaces:

FunctionEx<T,T,E>

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 UnaryOperatorEx<T,E extends java.lang.Throwable>
extends FunctionEx<T,T,E>

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.

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

1.8
