scala.collection.generic.MutableMapFactory

abstract class MutableMapFactory[CC[A, B] <: mutable.Map[A, B] with mutable.MapLike[A, B, CC[A, B]]] extends MapFactory[CC]

A template for companion objects of mutable.Map and subclasses thereof.

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

A collection of type Map that contains given key/value bindings.

  • elems
    • the key/value pairs that make up the map
  • returns
    • a new map consisting key/value pairs given by elems .

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

def toParArray: ParArray[T]

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

    • CollectionsHaveToParArray (added by implicit convertion: scala.collection.parallel.CollectionsHaveToParArray)
