iterator

public java.util.Iterator iterator()

Iteration is only supported on first-class (qualifiable) ranges, i.e. ranges of the type [lower..upper]. Qualified ranges, i.e. ranges of the type collection[lower..upper] are not directly iterable because we cannot provide the owning collection as context.

Specified by:

iterator in interface java.lang.Iterable

Returns:

an iterator over integer values.
