class TypedMultiMap[T <: AnyRef, K[_ <: T]] extends AnyRef
An immutable multi-map that expresses the value type as a type function of the key type. Create it with a type constructor that expresses the relationship:
trait Key { type Type = T } case class MyValue[T](...) // type function from Key to MyValue type KV[K <: Key] = MyValue[K#Type] val map = TypedMultiMap.empty[Key, KV] // a plain Int => String map would use this function: type plain[K <: Int] = String // a map T => T would use this function: type identity[T <: AnyRef] = T
Caveat: using keys which take type parameters does not work due to conflicts
with the existential interpretation of Key[_]
. A workaround is to define
a key type like above and provide a subtype that provides its type parameter
as type member Type
.

instead ofvalue.formatted(formatString)

string interpolator. In Java 15 and later,formatted
resolves to the new method in String which has reversed parameters.
