This trait extends the Scala 2.12 mutable.Map to implement the Scala 2.13 mutable.Map API.
This trait extends the Scala 2.12 mutable.Map to implement the Scala 2.13 mutable.Map API. This bridges the following source incompatibility:
- In Scala 2.11 and 2.12, +=
and -=
are abstract (must be implemented).
- In Scala 2.13, +=
and -=
are final (cannot be overridden). They are aliases for the
abstract addOne
and subtractOne
.
(Since version ) see corresponding Javadoc for more information.
