IntUnaryOperator (Java Platform SE 8 )

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 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).

Since:

1.8

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`default IntUnaryOperator`	`andThen(IntUnaryOperator after)` Returns a composed operator that first applies this operator to its input, and then applies the `after` operator to the result.
`int`	`applyAsInt(int operand)` Applies this operator to the given operand.
`default IntUnaryOperator`	`compose(IntUnaryOperator before)` Returns a composed operator that first applies the `before` operator to its input, and then applies this operator to the result.
`static IntUnaryOperator`	`identity()` Returns a unary operator that always returns its input argument.

- Method Detail
  - applyAsInt
```
int applyAsInt(int operand)
```
    Applies this operator to the given operand.
    
    Parameters:
    
    operand - the operand
    
    Returns:
    
    the operator result
  - compose
```
default IntUnaryOperator compose(IntUnaryOperator before)
```
    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 - the operator to apply before this operator is applied
    
    Returns:
    
    a composed operator that first applies the before operator and then applies this operator
    
    Throws:
    
    NullPointerException - if before is null
    
    See Also:
    
    andThen(IntUnaryOperator)
  - andThen
```
default IntUnaryOperator andThen(IntUnaryOperator after)
```
    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 - the operator to apply after this operator is applied
    
    Returns:
    
    a composed operator that first applies this operator and then applies the after operator
    
    Throws:
    
    NullPointerException - if after is null
    
    See Also:
    
    compose(IntUnaryOperator)
  - identity
```
static IntUnaryOperator identity()
```
    Returns a unary operator that always returns its input argument.
    
    Returns:
    
    a unary operator that always returns its input argument
