-
#adjacent?(o) ⇒ Boolean
Checks if this range is adjacent to the given range.
-
#each(&block) ⇒ Object
Returns Enumerator if no block is given Returns nil if size is infinity (does not yield).
-
#finite_range? ⇒ Boolean
Will respond ‘true` for any range that is bounded at both ends.
- #generalize ⇒ Object
- #instance?(o, guard = nil) ⇒ Boolean
- #iterable?(guard = nil) ⇒ Boolean
- #iterable_type(guard = nil) ⇒ Object
-
#merge(o) ⇒ PIntegerType?
Concatenates this range with another range provided that the ranges intersect or are adjacent.
- #new_function ⇒ Object
-
#range ⇒ Object
Returns the range as an array ordered so the smaller number is always first.
-
#size ⇒ Object
Returns Float.Infinity if one end of the range is unbound.
-
#to_size ⇒ PIntegerType
Returns a range where both to and from are positive numbers.
