Concrete Value Members From scala.collection.generic.GenMapFactory

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

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

• A
  • the type of the keys
• B
  • the type of the associated values
• elems
  • the key/value pairs that make up the map
• returns
  • a new map consisting key/value pairs given by elems .

def newBuilder[A, B]: Builder[(A, B), CC[A, B]]

The default builder for Map objects.

• A
  • the type of the keys
• B
  • the type of the associated values

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

def toParArray: ParArray[T]

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