In List§
See primary documentation in context for routine reverse
multi reverse(*@list --> Seq:D) multi method reverse(List:D: --> Seq:D)
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)»
In Any§
See primary documentation in context for routine reverse
multi reverse(*@list --> Seq:D) multi method reverse(List:D: --> Seq:D)
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)»
In Range§
See primary documentation in context for method reverse
method reverse(Range:D: --> Seq:D)
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 ...)»
In Mix§
See primary documentation in context for method reverse
Note: This method is inherited from Any, however, Mix
es do not have an inherent order and you should not trust it returning a consistent output.
In Supply§
See primary documentation in context for method reverse
method reverse(Supply:D: --> Supply:D)
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
quit
s, then the exception is immediately conveyed on the return Supply
.
my $s = Supply.from-list(1, 2, 3); my $t = $s.reverse; $t.tap(&say); # OUTPUT: «321»
In role Blob§
See primary documentation in context for method reverse
method reverse(Blob:D: --> Blob:D)
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>»
