def
nonEmptyListToList[E](nonEmptyList: NonEmptyList[E]): List[E]
Implicit conversion from
NonEmptyList
toList
.Implicit conversion from
NonEmptyList
toList
.One use case for this implicit conversion is to enable
GenSeq[NonEmptyList]
s to be flattened. Here's an example:scala> Vector(NonEmptyList(1, 2, 3), NonEmptyList(3, 4), NonEmptyList(5, 6, 7, 8)).flatten res0: scala.collection.immutable.Vector[Int] = Vector(1, 2, 3, 3, 4, 5, 6, 7, 8)
- nonEmptyList
the
NonEmptyList
to convert to aList
- returns
a
List
containing the elements, in order, of thisNonEmptyList
