IsMap

trait IsMap[Repr] extends IsIterable[Repr]

Type class witnessing that a collection type Repr has keys of type K, values of type V and has a conversion to MapOps[K, V, Iterable, C], for some types K, V and C.

This type enables simple enrichment of Maps with extension methods.

Type parameters:
Repr

Collection type (e.g. Map[Int, String])

The type returned by transformation operations that preserve the same elements type (e.g.

The type returned by transformation operations that preserve the same elements type (e.g. filter, take).

In practice, this type is often Repr itself, excepted in the case of SeqView[A] (and other View[A] subclasses), where it is “only” View[A].

Abstract methods

def apply(coll: Repr): IterableOps[A, Iterable, C]
Implicitly added by isMapLikeIsIterable

A conversion from the type Repr to IterableOps[A, Iterable, C]

A conversion from the type Repr to IterableOps[A, Iterable, C]

Source:
IsIterable.scala
override def apply(c: Repr): MapOps[K, V, <none>, C]

A conversion from the type Repr to MapOps[K, V, Iterable, C]

A conversion from the type Repr to MapOps[K, V, Iterable, C]

Note:

The third type parameter of the returned MapOps value is still Iterable (and not Map) because MapView[K, V] only extends MapOps[K, V, View, View[A]].
