Factory

trait Factory[-A, +C]

A factory that builds a collection of type C with elements of type A.

This is a general form of any factory (IterableFactory, SortedIterableFactory, MapFactory and SortedMapFactory) whose element type is fixed.

Type Params
A

Type of elements (e.g. Int, Boolean, etc.)

C

Type of collection (e.g. List[Int], TreeMap[Int, String], etc.)

Value Params
it

Source collection

Returns

A collection of type C containing the same elements as the source collection it.

Factory.scala
def newBuilder: Builder[A, C]

Get a Builder for the collection. For non-strict collection types this will use an intermediate buffer. Building collections with fromSpecific is preferred because it can be lazy for lazy collections.
