selectManyE<TResult> method
Maps elements in an enumerable to collections and then flattens those collections into a single enumerable.
During iteration, the selector
function is applied to each element. The
returned collection of that function is then iterated over, and each
value in that iteration is provided as the next element of the
resulting enumerable. The result is all the collections flattened so that
their values become elements in a single enumerable.
Implementation
Enumerable<TResult> selectManyE<TResult>(ManySelector<T, TResult> selector) {
assert(selector != null);
return SelectManyEnumerable<T, TResult>(this, selector);
}
