# cast<R> method

Queue<R> cast<R>()
override

A view of this iterable as an iterable of `R` instances.

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

When the returned iterable creates a new object that depends on the type `R`, e.g., from toList, it will have exactly the type `R`.

## Implementation

    Queue<R> cast<R>() => Queue.castFrom<E, R>(this);
