  7. def pipe[B](f: (A) ⇒ B): B

    Converts the value by applying the function f.

    Converts the value by applying the function f.

    scala> import scala.util.chaining._
    
    scala> val times6 = (_: Int) * 6
    times6: Int => Int = $$Lambda$2023/975629453@17143b3b
    
    scala> val i = (1 - 2 - 3).pipe(times6).pipe(scala.math.abs)
    i: Int = 24

    Note: (1 - 2 - 3).pipe(times6) may have a small amount of overhead at runtime compared to the equivalent { val temp = 1 - 2 - 3; times6(temp) }.

    B

    the result type of the function f.

    f

    the function to apply to the value.

    returns

    a new value resulting from applying the given function f to this value.

  8. def tap[U](f: (A) ⇒ U): A

    Applies f to the value for its side effects, and returns the original value.

    Applies f to the value for its side effects, and returns the original value.

    scala> import scala.util.chaining._
    
    scala> val xs = List(1, 2, 3).tap(ys => println("debug " + ys.toString))
    debug List(1, 2, 3)
    xs: List[Int] = List(1, 2, 3)
    U

    the result type of the function f.

    f

    the function to apply to the value.

    returns

    the original value self.
