cast<R> method
Provides 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
Iterable<R> cast<R>() => value.cast<R>();
