- 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 IntUnaryOperator Represents an operation on a singleint-valued operand that produces anint-valued result. This is the primitive type specialization ofUnaryOperatorforint.This is a functional interface whose functional method is applyAsInt(int).- Since:

Method Detail- 
applyAsIntint applyAsInt(int operand) Applies this operator to the given operand.- Parameters:
- operand- the operand
- Returns:
- the operator result
 
 - 
composedefault IntUnaryOperator compose(IntUnaryOperator before) Returns a composed operator that first applies thebeforeoperator to its input, and then applies this operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.- Parameters:
- before- the operator to apply before this operator is applied
- Returns:
- a composed operator that first applies the beforeoperator and then applies this operator
- Throws:
- NullPointerException- if before is null
- See Also:
- andThen(IntUnaryOperator)

andThendefault IntUnaryOperator andThen(IntUnaryOperator after) Returns a composed operator that first applies this operator to its input, and then applies theafteroperator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.- Parameters:
- after- the operator to apply after this operator is applied
- Returns:
- a composed operator that first applies this operator and then
 applies the afteroperator
- Throws:
- NullPointerException- if after is null
- See Also:
- compose(IntUnaryOperator)

identitystatic IntUnaryOperator identity() Returns a unary operator that always returns its input argument.- Returns:
- a unary operator that always returns its input argument
