  6. abstract def foreach(f: Consumer[A]): Unit

    Foreach override

    Foreach override

    foreach is the most widely used Stream method, which largely determines general performance

    Default implementation looks like

    def foreach(c: Stream.Consumer[A]) = while (prime) c.accept(pump)

    If custom Stream can do better, this method should be overridden

  12. def preview(cnt: Int): ~[A]

    Preview multiple elements

    Preview multiple elements

    Returns a Stream of elements waiting to be primed and pumped

    Definition Classes
    Indexed → Preview
  13. def previewNextOpt: Opt[A]

    Preview next element

    Preview next element

    Optionally returns next element, which can be primed and pumped

    Indexed → Preview
  14. def previewSize: Int

    Preview element count

    Preview element count

    If metadata sizeOpt is not empty, the value is returned

    Otherwise calls primeAll

    Definition Classes
    Indexed → Preview
  15. def previewSizeAtLeast(cnt: Int): Boolean

    Checks size up to a limit

    Checks size up to a limit

    Retuns true if the element count is equal or exceeding the specified

    If metadata sizeOpt is not empty, the value is tested

    Otherwise, tries to prime requested number of elements

    Indexed → Preview
  16. def prime(cnt: Int): Int

    Requests to get several elements ready

    Requests to get several elements ready

    Parameter indicates how many elements are requested

    Returns actual primed elements count

    Returned value can be less than requested if Stream is exhausted, or greater, if more elements are ready

  17. def prime: Boolean

  19. def sizeOpt: Opt.Int

    Current size option

    Current size option

    By default sizeOpt returns Opt.Void

    If custom Stream knows current size, this could greatly help optimizations

    Indexed → Defaults
  20. def sortedOpt: Opt[Comparator[A]]

    Current sorted option

    Current sorted option

    By default sortedOpt returns Opt.Void

    If custom Stream is sorted, return the Ordering

  22. def takeWhile(f: Filter[A]): ~[A]

    Stream while

    Stream while

    Returns a Stream of sequential elements, which pass given filter

    Note. Streamed elements are immediately removed from this Stream and buffered within the returned new Stream

  24. def typeOpt: Opt[Util.Specialized.Type]
