Package it.unimi.dsi.fastutil.shorts

Interface ShortUnaryOperator

All Superinterfaces:

Function<Short,Short>, IntUnaryOperator, UnaryOperator<Short>

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 ShortUnaryOperator
extends UnaryOperator<Short>, IntUnaryOperator

A type-specific UnaryOperator; provides methods operating both on objects and on primitives.

Since:

8.5.0

See Also:

• UnaryOperator

Method Summary

Modifier and Type	Method	Description
short	apply(short x)	Computes the operator on the given input.
default Short	apply(Short x)	Deprecated. Please use the corresponding type-specific method instead.
default int	applyAsInt(int x)	Deprecated. Please use apply(short).
static ShortUnaryOperator	identity()	Returns a UnaryOperator that always returns the input unmodified.
static ShortUnaryOperator	negation()	Returns a UnaryOperator that always returns the arithmetic negation of the input.

Method Details

apply

short apply(short x)

Computes the operator on the given input.

Parameters:

x - the input.

Returns:

the output of the operator on the given input.

identity

static ShortUnaryOperator identity()

Returns a UnaryOperator that always returns the input unmodified.

See Also:

• UnaryOperator.identity()

negation

static ShortUnaryOperator 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(short).

Specified by:

applyAsInt in interface IntUnaryOperator

Throws:

IllegalArgumentException - If the given operands are not an element of the key domain.

Since:

8.5.0

Implementation Specification:

This default implementation delegates to apply(short) after narrowing down the argument to the actual key type, throwing an exception if the argument cannot be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. The use of this method discouraged, as unexpected errors can occur.

apply

@Deprecated
default Short apply(Short x)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

apply in interface Function<Short,Short>
