Trait BuildFrom.BuildFrom

trait BuildFrom[-From, -A, +C]

Builds a collection of type C from elements of type A when a source collection of type From is available. Implicit instances of BuildFrom are available for all collection types.

Type parameters	A Type of elements (e.g. Int, Boolean, etc.) C Type of collection (e.g. List[Int], TreeMap[Int, String], etc.) From Type of source collection
Supertypes	class Any
Self type	BuildFrom[From, A, C]

Abstract methods

Source

def fromSpecific(from: From)(it: IterableOnce[A]): C

Source

def newBuilder(from: From): 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.

Concrete methods

Source

def toFactory(from: From): Factory[A, C]

Partially apply a BuildFrom to a Factory
