# cast<R> abstract method

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 read 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 instances of `R` to be valid arguments to the adding function, and they must also be instances of `E` to be accepted by this list as well.

Methods which accept `Object?` as argument, like contains and remove, will pass the argument directly to the this list's method without any checks. That means that you can do `listOfStrings.cast<int>().remove("a")` successfully, even if it looks like it shouldn't have any effect.

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

## Implementation
