class ObjectRange
Description
Ranges represent an interval of values. The value type just needs to be
"compatible" — that is, to implement a succ method letting us step from
one value to the next (its successor).
Prototype provides such a method for Number and String, but you
are (of course) welcome to implement useful semantics in your own objects,
in order to enable ranges based on them.
ObjectRange mixes in Enumerable, which makes ranges very versatile.
It takes care, however, to override the default code for include, to
achieve better efficiency.
While ObjectRange does provide a constructor, the preferred way to obtain
a range is to use the $R utility function, which is strictly equivalent
(only way more concise to use).
Constructor
new ObjectRange(start, end[, exclusive = false])Creates a new ObjectRange.
The exclusive argument specifies whether end itself is a part of the
range.
Instance methods
-
include
ObjectRange#include(value) -> BooleanDetermines whether the value is included in the range.
