Creates a wrapper that asserts the types of keys and values in base
.
This soundly converts a Map without generic types to a Map<K, V>
by
asserting that its keys are instances of E
and its values are instances
of V
whenever they're accessed. If they're not, it throws a CastError.
Note that even if an operation throws a CastError, it may still mutate
the underlying collection.
This forwards all operations to base
, so any changes in base
will be
reflected in this. If base
is already a Map<K, V>
, it's returned
unmodified.

static Map<K, V> typed<K, V>(Map base) => base.cast<K, V>();
