IntUnaryOperator (fastutil 8.5.15)

All Superinterfaces:

java.util.function.Function<java.lang.Integer,java.lang.Integer>, java.util.function.IntUnaryOperator, java.util.function.UnaryOperator<java.lang.Integer>

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
extends java.util.function.UnaryOperator<java.lang.Integer>, java.util.function.IntUnaryOperator
```

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods Deprecated Methods
Modifier and Type	Method	Description
`int`	`apply(int x)`	Computes the operator on the given input.
`default java.lang.Integer`	`apply(java.lang.Integer x)`	Deprecated. Please use the corresponding type-specific method instead.
`default int`	`applyAsInt(int x)`	Deprecated. Please use `apply(int)`.
`static IntUnaryOperator`	`identity()`	Returns a `UnaryOperator` that always returns the input unmodified.
`static IntUnaryOperator`	`negation()`	Returns a `UnaryOperator` that always returns the arithmetic negation of the input.

- Method Detail
  - apply
```
int apply(int x)
```
    Computes the operator on the given input.
    
    Parameters:
    
    x - the input.
    
    Returns:
    
    the output of the operator on the given input.
  - identity
```
static IntUnaryOperator identity()
```
    Returns a UnaryOperator that always returns the input unmodified.
    
    See Also:
    
    UnaryOperator.identity()
  - negation
```
static IntUnaryOperator negation()
```
    Returns a UnaryOperator that always returns the arithmetic negation of the input.
    
    Implementation Notes:
    
    As with all negation, be wary of unexpected behavior near the minimum value of the data type. For example, -Integer.MIN_VALUE will result in Integer.MIN_VALUE (still negative), as the positive value of Integer.MIN_VALUE is too big for int (it would be 1 greater then Integer.MAX_VALUE).
  - applyAsInt
```
@Deprecated
default int applyAsInt(int x)
```
    Deprecated.
    Please use apply(int).
    
    Specified by:
    
    applyAsInt in interface java.util.function.IntUnaryOperator
    
    Implementation Specification:
    
    This default implementation delegates to apply(int).
  - apply
```
@Deprecated
default java.lang.Integer apply(java.lang.Integer x)
```
    Deprecated.
    Please use the corresponding type-specific method instead.
