Venus::Array - Array Class

ABSTRACT

Array Class for Perl 5

SYNOPSIS

  package main;

  use Venus::Array;

  my $array = Venus::Array->new([1..9]);

  # $array->random;

DESCRIPTION

This package provides methods for manipulating array data.

INHERITS

This package inherits behaviors from:

Venus::Kind::Value

INTEGRATES

This package integrates behaviors from:

Venus::Role::Mappable

METHODS

This package provides the following methods:

all

  all(CodeRef $code) (Bool)

The all method returns true if the callback returns true for all of the elements.

Since 0.01

all example 1

  # given: synopsis;

  my $all = $array->all(sub {
    $_ > 0;
  });

  # 1

all example 2

  # given: synopsis;

  my $all = $array->all(sub {
    my ($key, $value) = @_;

    $value > 0;
  });

  # 1

any

  any(CodeRef $code) (Bool)

The any method returns true if the callback returns true for any of the elements.

Since 0.01

any example 1

  # given: synopsis;

  my $any = $array->any(sub {
    $_ > 4;
  });

any example 2

  # given: synopsis;

  my $any = $array->any(sub {
    my ($key, $value) = @_;

    $value > 4;
  });

call

  call(Str $iterable, Str $method) (Any)

The call method executes the given method (named using the first argument) which performs an iteration (i.e. takes a callback) and calls the method (named using the second argument) on the object (or value) and returns the result of the iterable method.

Since 1.02

call example 1

  # given: synopsis

  package main;

  my $call = $array->call('map', 'incr');

  # [2..10]

call example 2

  # given: synopsis

  package main;

  my $call = $array->call('grep', 'gt', 4);

  # [4..9]

cast

  cast(Str $kind) (Object | Undef)

The cast method converts "value" objects between different "value" object types, based on the name of the type provided. This method will return undef if the invocant is not a Venus::Kind::Value.

Since 0.08

  my $array = Venus::Array->new;

  my $cast = $array->cast('boolean');

  # bless({ value => 1 }, "Venus::Boolean")

cast example 3

  package main;

  use Venus::Array;

  my $array = Venus::Array->new;

  use Venus::Array;

  my $array = Venus::Array->new;

  my $cast = $array->cast('float');

  # bless({ value => "1.0" }, "Venus::Float")

cast example 5

  my $array = Venus::Array->new;

  my $cast = $array->cast('number');

  # bless({ value => 2 }, "Venus::Number")

cast example 7

  package main;

  use Venus::Array;

  my $array = Venus::Array->new;

  my $cast = $array->cast('regexp');
