Attributes

Returns

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

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

Gets 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.
