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.
