Implicit conversion from NonEmptyMap
to Map
.
Implicit conversion from NonEmptyMap
to Map
.
One use case for this implicit conversion is to enable GenSeq[NonEmptyMap]
s to be flattened. Here's an example:
scala> Vector(NonEmptyMap(1, 2, 3), NonEmptyMap(3, 4), NonEmptyMap(5, 6, 7, 8)).flatten res0: scala.collection.immutable.Vector[Int] = Vector(1, 2, 3, 3, 4, 5, 6, 7, 8)
Type parameters
- K
-
the type of the key contained in the
NonEmptyMap
- V
-
the type of the value contained in the
NonEmptyMap
Value parameters
- nonEmptyMap
-
the
NonEmptyMap
to convert to aMap
Attributes
- Returns
-
a
Map
containing the elements, in order, of thisNonEmptyMap
