# cast<R> method Null safety

List<R> cast <R>()
override

Returns a view of this list as a list of `R` instances.

If this list contains only instances of `R`, all read operations will work correctly. If any operation tries to access an element that is not an instance of `R`, the access will throw instead.

Elements added to the list (e.g., by using add or addAll) must be instance of `R` to be valid arguments to the adding function, and they must be instances of `E` as well to be accepted by this list as well.

Typically implemented as `List.castFrom<E, R>(this)`.

## Implementation

    List<R> cast<R>();
