# map<T> method

Iterable<T> map <T>(T f(E element))
inherited

Returns a new lazy Iterable with elements that are created by calling `f` on each element of this `Iterable` in iteration order.

This method returns a view of the mapped elements. As long as the returned Iterable is not iterated over, the supplied function `f` will not be invoked. The transformed elements will not be cached. Iterating multiple times over the returned Iterable will invoke the supplied function `f` multiple times on the same element.

Methods on the returned iterable are allowed to omit calling `f` on any element where the result isn't needed. For example, elementAt may call `f` only once.

## Implementation

    Iterable<T> map<T>(T f(E element)) => new MappedListIterable<E, T>(this, f);
