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 include, and is way more efficient (it uses a maximum of two comparisons).

 

Examples

 

$R(110).include(5)

// -> true

 

$R('a''h').include('x')

// -> false

 

$R(110).include(10)

// -> true

 

$R(110true).include(10)

// -> false
