Range Class

A range defines a bounded range of values from a starting point to a possibly exclusive endpoint. Here is a friendly introduction.

Extends Sequence.

Methods #

from #

The starting point of the range. A range may be backwards, so this can be greater than [to].

System.print((3..5).min) 3
System.print((4..2).min) 4

to #

The endpoint of the range. If the range is inclusive, this value is included, otherwise it is not.

System.print((3..5).min) 5
System.print((4..2).min) 2

min #

The minimum bound of the range. Returns either from, or to, whichever is lower.

System.print((3..5).min) 3
System.print((4..2).min) 2

max #

The maximum bound of the range. Returns either from, or to, whichever is greater.

System.print((3..5).min) 5
System.print((4..2).min) 4

isInclusive #

Whether or not the range includes to. (from is always included.)

System.print((3..5).isInclusive)   true
System.print((3...5).isInclusive)  false

iterate(iterator), iteratorValue(iterator) #

Iterates over the range. Starts at from and increments by one towards to until the endpoint is reached.
