scala.collection.generic.GenSetFactory

abstract class GenSetFactory[CC[X] <: GenSet[X] with GenSetLike[X, CC[X]]] extends GenericCompanion[CC]

A template for companion objects of Set and subclasses thereof.

Type Members

Concrete Value Members From scala.collection.generic.GenericCompanion

def apply[A](elems: A*): CC[A]

Creates a collection with the specified elements.

  • A
    • the type of the collection’s elements
  • elems
    • the elements of the created collection

Concrete Value Members From Implicit scala.collection.parallel.CollectionsHaveToParArray ——————————————————————————–

def toParArray: ParArray[T]

  • Implicit information
    • This member is added by an implicit conversion from GenSetFactory [CC] to CollectionsHaveToParArray [GenSetFactory [CC], T] performed by method CollectionsHaveToParArray in scala.collection.parallel. This conversion will take place only if an implicit value of type (GenSetFactory [CC]) ⇒ GenTraversableOnce [T] is in scope.
  • Definition Classes
    • CollectionsHaveToParArray (added by implicit convertion: scala.collection.parallel.CollectionsHaveToParArray)
