Slots

contains

Bool contains(Int i)

Return if this range contains the specified integer.

Example:

(1..3).contains(2)  =>  true
(1..3).contains(4)  =>  false

each

Void each(|Int| c)

Call the specified function for each integer in the range.

Example:

('a'..'z').each |Int i| { echo(i) }

end

Int end()

Return end index.

Example:

(1..3).end  =>  3

equals

override Bool equals(Obj? obj)

Overrides sys::Obj.equals

Return true if same start, end, and exclusive.

exclusive

Bool exclusive()

Is the end index exclusive.

Example:

(1..3).exclusive   =>  false
(1..<3).exclusive  =>  true

first

Int? first()

Get the first value of the range. If range contains no values then return null. Equivalent to toList.first.

fromStr

static Range? fromStr(Str s, Bool checked := true)

Parse from string format - inclusive is "start..end", or exclusive is "start..<end". If invalid format then throw ParseErr or return null based on checked flag.

hash

override Int hash()

Overrides sys::Obj.hash

Return start ^ end.

inclusive

Bool inclusive()

Is the end index inclusive.

Example:

(1..3).inclusive   =>  true
(1..<3).inclusive  =>  false

isEmpty

Bool isEmpty()

Return if this range contains no integer values. Equivalent to toList.isEmpty.

last

Int? last()

Get the last value of the range. If range contains no values then return null. Equivalent to toList.last.

make

new make(Int start, Int end, Bool exclusive)

Constructor with start, end, and exclusive flag (all must be non-null).

makeExclusive

new makeExclusive(Int start, Int end)

Convenience for make(start, end, true).

makeInclusive

new makeInclusive(Int start, Int end)

Convenience for make(start, end, false).

map

Obj?[] map(|Int -> Obj?| c)

Create a new list which is the result of calling c for every integer in the range. The new list is typed based on the return type of c.

Example:

(10..15).map |i->Str| { i.toHex }  =>  Str[a, b, c, d, e, f]

max

Int? max()

Get the maximum value of the range. If range contains no values then return null. Equivalent to toList.max.

min

Int? min()

Get the minimum value of the range. If range contains no values then return null. Equivalent to toList.min.

offset

Range offset(Int offset)

Create a new range by adding offset to this range's start and end values.

Example:

(3..5).offset(2)   =>  5..7
(3..<5).offset(-2) =>  1..<3

random

Int random()

Convenience for Int.random(this).

start

Int start()

Return start index.

Example:

(1..3).start  =>  1

toList

Int[] toList()

Convert this range into a list of Ints.

Example:

(2..4).toList   =>  [2,3,4]
(2..<4).toList  =>  [2,3]
(10..8).toList  =>  [10,9,8]

toStr

override Str toStr()

Overrides sys::Obj.toStr

If inclusive return "start..end", if exclusive return "start..<end".
