Value parameters:
it

Source collection

Returns:

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

Source:
Factory.scala
def newBuilder(from: From): Builder[A, C]
Implicitly added by toBuildFrom

Get a Builder for the collection.

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.
