Documentation for routine reverse assembled from the following pages:
Class: Any §
From Any
(Any) routine reverse §
Defined as:
multi sub reverse(* --> Seq)multi method reverse(List: --> Seq)Returns a Seq with the same elements in reverse order.
Note that reverse always refers to reversing elements of a list; to reverse the characters in a string, use flip.
Examples:
say <hello world!>.reverse; # OUTPUT: «(world! hello)» say reverse ^10; # OUTPUT: «(9 8 7 6 5 4 3 2 1 0)»Role: Blob §
From Blob
(Blob) method reverse §
Defined as:
method reverse(Blob: --> Blob)Returns a Blob with all elements in reversed order.
say Blob.new([1, 2, 3]).reverse; # OUTPUT: «Blob:0x<03 02 01>» say blob16.new([2]).reverse; # OUTPUT: «Blob[uint16]:0x<02>» say blob32.new([16, 32]).reverse; # OUTPUT: «Blob[uint32]:0x<20 10>»Class: Supply §
From Supply
(Supply) method reverse §
method reverse(Supply: --> Supply)Taps the Supply it is called on. Once that Supply emits done, all of the values it emitted will be emitted on the returned Supply in reverse order. If the original Supply quits, then the exception is immediately conveyed on the return Supply.
my = Supply.from-list(1, 2, 3);my = .reverse;.tap(); # OUTPUT: «321»Class: List §
From List
(List) routine reverse §
Defined as:
multi sub reverse(* --> Seq)multi method reverse(List: --> Seq)Returns a Seq with the same elements in reverse order.
Note that reverse always refers to reversing elements of a list; to reverse the characters in a string, use flip.
Examples:
say <hello world!>.reverse; # OUTPUT: «(world! hello)» say reverse ^10; # OUTPUT: «(9 8 7 6 5 4 3 2 1 0)»Class: Mix §
From Mix
(Mix) method reverse §
Note: This method is inherited from Any, however, Mixes do not have an inherent order and you should not trust it returning a consistent output.
Class: Range §
From Range
(Range) method reverse §
method reverse(Range: --> Seq)Returns a Seq where all elements that the Range represents have been reversed. Note that reversing an infinite Range won't produce any meaningful results.
say (1^..5).reverse; # OUTPUT: «(5 4 3 2)» say ('a'..'d').reverse; # OUTPUT: «(d c b a)» say (1..∞).reverse; # OUTPUT: «(Inf Inf Inf ...)»
