IntUnaryOperator

  • IntUnaryOperator is a functional interface representing an operation on a single int input that produces an int output.

  • It provides methods to apply the operation (applyAsInt), chain operations (andThen, compose), and get an identity operator (identity).

  • This interface is a specialization of UnaryOperator for primitive int values.
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).

Public Method Summary

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.
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

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 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

public abstract int applyAsInt (int operand)

Applies this operator to the given operand.

Parameters
operand the operand
Returns
  • the operator result

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 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

public static IntUnaryOperator identity ()

Returns a unary operator that always returns its input argument.

Returns
  • a unary operator that always returns its input argument
