trait Subtractable[A, +Repr <: Subtractable[A, Repr]] extends AnyRef

This trait represents collection-like objects that can be reduced using a '+' operator. It defines variants of - and -- as convenience methods in terms of single-element removal -.

A

the type of the elements of the collection.

Repr

the type of the collection itself

Abstract Value Members

  1. abstract def -(elem: A): Repr

    Creates a new collection from this collection with an element removed.

    Creates a new collection from this collection with an element removed.

    elem

    the element to remove

    returns

    a new collection that contains all elements of the current collection except one less occurrence of elem.

  2. abstract def repr: Repr

    Creates a new collection from this collection with some elements removed.

    Creates a new collection from this collection with some elements removed.

    This method takes two or more elements to be removed. Another overloaded variant of this method handles the case where a single element is removed.

    elem1

    the first element to remove.

    elem2

    the second element to remove.

    elems

    the remaining elements to remove.

    returns

    a new collection that contains all elements of the current collection except one less occurrence of each of the given elements.

  4. def --(xs: GenTraversableOnce[A]): Repr

    Permalink

    Creates a new collection from this collection by removing all elements of another collection.

    Creates a new collection from this collection by removing all elements of another collection.

    xs

    the collection containing the removed elements.

    returns

    a new collection that contains all elements of the current collection except one less occurrence of each of the elements of elems.
