abstract class WithFilter[+A, +CC[_]] extends AnyRef

A template trait that contains just the map, flatMap, foreach and withFilter methods of trait Iterable.

A

Element type (e.g. Int)

CC

Collection type constructor (e.g. List)

Abstract Value Members

  1. abstract def flatMap[B](f: (A) ⇒ IterableOnce[B]): CC[B]

    Builds a new collection by applying a function to all elements of the filtered outer collection containing this WithFilter instance that satisfy

    Builds a new collection by applying a function to all elements of the filtered outer collection containing this WithFilter instance that satisfy

    B

    the element type of the returned collection.

    f

    the function to apply to each element.

    returns

    a new collection resulting from applying the given collection-valued function f to each element of the filtered outer collection and concatenating the results.

  2. abstract def foreach[U](f: (A) ⇒ U): Unit

    Applies a function f to all elements of the filtered outer collection.

    Applies a function f to all elements of the filtered outer collection.

    U

    the type parameter describing the result of function f. This result will always be ignored. Typically U is Unit, but this is not necessary.

    f

    the function that is applied for its side-effect to every element. The result of function f is discarded.

  3. abstract def map[B](f: (A) ⇒ B): CC[B]

    Builds a new collection by applying a function to all elements of the filtered outer collection.

    Builds a new collection by applying a function to all elements of the filtered outer collection.

    B

    the element type of the returned collection.

    f

    the function to apply to each element.

    returns

    a new collection resulting from applying the given function f to each element of the filtered outer collection and collecting the results.

  4. abstract def withFilter(q: (A) ⇒ Boolean): WithFilter[A, CC]

    Further refines the filter for this filtered collection.

    Further refines the filter for this filtered collection.

    q

    the predicate used to test elements.

    returns

    an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this collection which also satisfy both p and q predicates.
