Interface FloatUnaryOperator

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 FloatUnaryOperator
Represents an operation that takes a float-valued operand and produces a float-valued result. This is a specialization of UnaryOperator for float.

This is a functional interface whose functional method is applyAsFloat(float).

  • Method Summary

    Modifier and Type
    Method
    Description
    default FloatUnaryOperator
    andThen(FloatUnaryOperator after)
    Creates a "forward" composed operator that first applies this operator to its input, and then applies the after operator to the result.
    float
    applyAsFloat(float operand)
    Applies this operator.
    default FloatUnaryOperator
    compose(FloatUnaryOperator before)
    Creates a "backward" composed operator that first applies the before operator to its input, and then applies this operator to the result.
    static FloatUnaryOperator
    identity()
    Returns the identity float unary operator.

  • Method Details

    • applyAsFloat

      float applyAsFloat(float operand)
      Applies this operator.
      Parameters:
      operand - the operand
      Returns:
      the operator result

    • compose

      default FloatUnaryOperator compose(FloatUnaryOperator before)
      Creates a "backward" composed operator that first applies the before operator to its input, and then applies this operator to the result.
      Parameters:
      before - the operator to apply before this operator is applied
      Returns:
      the composed operator
      Throws:
      NullPointerException - if before is null

    • andThen

      default FloatUnaryOperator andThen(FloatUnaryOperator after)
      Creates a "forward" composed operator that first applies this operator to its input, and then applies the after operator to the result.
      Parameters:
      after - the operator to apply after this operator is applied
      Returns:
      the composed operator
      Throws:
      NullPointerException - if after is null

    • identity

      static FloatUnaryOperator identity()
      Returns the identity float unary operator.
      Returns:
      a unary operator that always returns its input argument
