public 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).

Summary

Public methods
`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.
`abstract 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.

Public methods

andThen

public 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`	`IntUnaryOperator`: the operator to apply after this operator is applied

Returns
`IntUnaryOperator`	a composed operator that first applies this operator and then applies the `after` operator

Throws
`NullPointerException`	if after is null

applyAsInt

public abstract int applyAsInt (int operand)

Applies this operator to the given operand.

Parameters
`operand`	`int`: the operand

Returns
`int`	the operator result

compose

public 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`	`IntUnaryOperator`: the operator to apply before this operator is applied

Returns
`IntUnaryOperator`	a composed operator that first applies the `before` operator and then applies this operator

Throws
`NullPointerException`	if before is null

identity

public static IntUnaryOperator identity ()

Returns a unary operator that always returns its input argument.

Returns
`IntUnaryOperator`	a unary operator that always returns its input argument
