typed<E> static method
Creates a wrapper that asserts the types of values in base.
This soundly converts an Iterable without a generic type to an
Iterable<E> by asserting that its elements are instances of E whenever
they're accessed. If they're not, it throws a TypeError.
This forwards all operations to base, so any changes in base will be
reflected in this. If base is already an Iterable<E>, it's returned
unmodified.
Implementation
@Deprecated('Use iterable.cast<E> instead.')
static Iterable<E> typed<E>(Iterable base) => base.cast<E>();
