IntUnaryOperator
@FunctionalInterface interface IntUnaryOperator
| java.util.function.IntUnaryOperator |
Represents an operation on a single int-valued operand that produces an int-valued result. This is the primitive type specialization of UnaryOperator for int.
This is a functional interface whose functional method is applyAsInt(int).

Public methods
andThen
open fun andThen(after: IntUnaryOperator!): IntUnaryOperator!
Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.
| Parameters | |
|---|---|
after |
IntUnaryOperator!: the operator to apply after this operator is applied |
| Return | |
|---|---|
IntUnaryOperator! |
a composed operator that first applies this operator and then applies the after operator |
| Exceptions | |
|---|---|
java.lang.NullPointerException |
if after is null |

applyAsInt
abstract fun applyAsInt(operand: Int): Int
Applies this operator to the given operand.
| Parameters | |
|---|---|
operand |
Int: the operand |
| Return | |
|---|---|
Int |
the operator result |
compose
open fun compose(before: IntUnaryOperator!): IntUnaryOperator!
Returns a composed operator that first applies the before operator 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 |
IntUnaryOperator!: the operator to apply before this operator is applied |
| Return | |
|---|---|
IntUnaryOperator! |
a composed operator that first applies the before operator and then applies this operator |
| Exceptions | |
|---|---|
java.lang.NullPointerException |
if before is null |

identity
open static fun identity(): IntUnaryOperator!
Returns a unary operator that always returns its input argument.
| Return | |
|---|---|
IntUnaryOperator! |
a unary operator that always returns its input argument |
