instance method ObjectRange#include
ObjectRange#include(value) → Boolean
Determines whether the value is included in the range.
This assumes the values in the range have a valid strict weak ordering
(have valid semantics for the <
operator). While ObjectRange
mixes
in Enumerable
, this method overrides the default version of
Enumerable#include
, and is much more efficient (it uses a maximum of
two comparisons).
Examples
$R(1, 10).include(5);
// -> true
$R('a', 'h').include('x');
// -> false
$R(1, 10).include(10);
// -> true
$R(1, 10, true).include(10);
// -> false
