Value Members

  1. def andThen[A](g: (R) => A): (Double) => A

    Composes two instances of Function1 in a new Function1, with this function applied first.

    Composes two instances of Function1 in a new Function1, with this function applied first.

    A

    the result type of function g

    g

    a function R => A

    returns

    a new function f such that f(x) == g(apply(x))

    @unspecialized()
  2. def apply(x1: Double): R

    Apply the body of this function to the argument.

    Apply the body of this function to the argument.

    returns

    the result of function application.

    FromJavaDoubleFunctionFunction1
  3. def compose[A](g: (A) => Double): (A) => R

    Composes two instances of Function1 in a new Function1, with this function applied last.

    Composes two instances of Function1 in a new Function1, with this function applied last.

    A

    the type to which function g can be applied

    g

    a function A => T1

    returns

    a new function f such that f(x) == apply(g(x))

  4. val jf: DoubleFunction[R]
  5. def productElementNames: Iterator[String]

    An iterator over the names of all the elements of this product.

    An iterator over the names of all the elements of this product.

    Definition Classes
    Product
  6. def toString(): String

    Creates a String representation of this object.

    Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

    returns

    a String representation of the object.

    Definition Classes
    Function1 → AnyRef → Any
  7. def unlift: PartialFunction[Double, B]

    Converts an optional function to a partial function.

    Converts an optional function to a partial function.

    Implicit
    This member is added by an implicit conversion from FromJavaDoubleFunction[R] toUnliftOps[Double, B] performed by method UnliftOps in scala.Function1.This conversion will take place only if R is a subclass of Option[B] (R <: Option[B]).
    Definition Classes
    UnliftOps
    Example:
    1. Unlike Function.unlift, this UnliftOps.unlift method can be used in extractors.

      val of: Int => Option[String] = { i =>
        if (i == 2) {
          Some("matched by an optional function")
        } else {
          None
        }
      }
      
      util.Random.nextInt(4) match {
        case of.unlift(m) => // Convert an optional function to a pattern
          println(m)
        case _ =>
          println("Not matched")
      }
