Abstract Value Members

  1. abstract def apply(): Builder[Elem, To]

    Creates a new builder from scratch.

    Creates a new builder from scratch.

    returns

    a builder for collections of type To with element type Elem.

  2. abstract def apply(from: From): Builder[Elem, To]

    Creates a new builder on request of a collection.

    Creates a new builder on request of a collection.

    from

    the collection requesting the builder to be created.

    returns

    a builder for collections of type To with element type Elem. The collections framework usually arranges things so that the created builder will build the same kind of collection as from.
