Mojo::Collection - Collection
# Manipulate collections use Mojo::Collection; my $collection = Mojo::Collection->new(qw(just works)); unshift @$collection, 'it'; $collection->map(sub { ucfirst })->each(sub { my ($word, $count) = @_; say "$count: $word"; }); # Use the alternative constructor use Mojo::Collection 'c'; c(qw(a b c))->join('/')->url_escape->say;
Mojo::Collection is a container for collections.
Mojo::Collection implements the following functions.
my $collection = c(1, 2, 3);
Construct a new array-based Mojo::Collection object.
Mojo::Collection inherits all methods from Mojo::Base and implements the following new ones.
my $collection = Mojo::Collection->new(1, 2, 3);
my @elements = $collection->each; $collection = $collection->each(sub {...});
Evaluate callback for each element in collection.
$collection->each(sub { my ($e, $count) = @_; say "$count: $e"; });
my $first = $collection->first; my $first = $collection->first(qr/foo/); my $first = $collection->first(sub {...});
Evaluate regular expression or callback for each element in collection and return the first one that matched the regular expression, or for which the callback returned true.
my $five = $collection->first(sub { $_ == 5 });
my $new = $collection->grep(qr/foo/); my $new = $collection->grep(sub {...});
Evaluate regular expression or callback for each element in collection and create a new collection with all elements that matched the regular expression, or for which the callback returned true.
my $interesting = $collection->grep(qr/mojo/i);
my $stream = $collection->join("\n");
Turn collection into Mojo::ByteStream.
$collection->join("\n")->say;
my $new = $collection->map(sub {...});
Evaluate callback for each element in collection and create a new collection from the results.
my $doubled = $collection->map(sub { $_ * 2 });
my $new = $collection->pluck($method); my $new = $collection->pluck($method, @args);
Call method on each element in collection and create a new collection from the results.
# Equal to but more convenient than my $new = $collection->map(sub { $_->$method(@args) });
my $new = $collection->reverse;
Create a new collection with all elements in reverse order.
my $new = $collection->slice(4 .. 7);
Create a new collection with all selected elements.
my $new = $collection->shuffle;
Create a new collection with all elements in random order.
my $size = $collection->size;
Number of elements in collection.
my $new = $collection->sort; my $new = $collection->sort(sub {...});
Sort elements based on return value of callback and create a new collection from the results.
my $insensitive = $collection->sort(sub { uc(shift) cmp uc(shift) });
my $new = $collection->uniq;
Create a new collection without duplicate elements.
Direct array reference access to elements is also possible.
say $collection->[23]; say for @$collection;
