OpenJDK 27 · java.util.function.IntUnaryOperator · APIdia, the JavaDoc alternative

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).

Method Summary

Modifier and Type	Method and Description
public default IntUnaryOperator	Returns: a composed operator that first applies this operator and then applies the `after` operator andThen(IntUnaryOperator the operator to apply after this operator is applied after) Returns a composed operator that first applies this operator to its input, and then applies the `after` operator to the result.
public int	Returns: the operator result applyAsInt(int the operand operand) Applies this operator to the given operand.
public default IntUnaryOperator	Returns: a composed operator that first applies the `before` operator and then applies this operator compose(IntUnaryOperator the operator to apply before this operator is applied before) Returns a composed operator that first applies the `before` operator to its input, and then applies this operator to the result.
public static IntUnaryOperator	Returns: a unary operator that always returns its input argument identity() Returns a unary operator that always returns its input argument.

andThen	back to summary
public 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: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 Exceptions NullPointerException: if after is null See Also `compose(IntUnaryOperator)`

public 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: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

Exceptions

NullPointerException:: if after is null

compose	back to summary
public 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: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 Exceptions NullPointerException: if before is null See Also `andThen(IntUnaryOperator)`

public 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: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

Exceptions

NullPointerException:: if before is null
