MooX::Types::MooseLike::Base - Moose like types for Moo
package MyPackage; use Moo; use MooX::Types::MooseLike::Base qw(:all); has "beers_by_day_of_week" => ( isa => HashRef ); has "current_BAC" => ( isa => Num ); # Also supporting is_$type. For example, is_Int() can be used as follows has 'legal_age' => ( is => 'ro', isa => sub { die "$_[0] is not of legal age" unless (is_Int($_[0]) && $_[0] > 17) }, );
Moo attributes (like Moose) have an 'isa' property. This module provides some basic types for this property. One can import all types with ':all' tag or import a list of types like:
use MooX::Types::MooseLike::Base qw/HashRef ArrayRef/;
so one could then declare some attributtes like:
has 'contact' => ( is => 'ro', isa => HashRef, ); has 'guest_list' => ( is => 'ro', isa => ArrayRef[HashRef], );
These types provide a check that the contact attribute is a hash reference, and that the guest_list is an array of hash references.
hash
array of hash
Any type (test is always true)
Synonymous with Any type
A type that is not defined
A type that is defined
A boolean 1|0 type
A non-reference type
A reference type
A non-reference type where a reference to it is a SCALAR
A number type
An integer type
An ArrayRef (ARRAY) type
A HashRef (HASH) type
A CodeRef (CODE) type
A regular expression reference type
A glob reference type
A type that is either a builtin perl filehandle or an IO::Handle object
A type that is an object (think blessed)
The following types can be parameterized with other types.
For example, ArrayRef[HashRef]
For example, Maybe[Int] would be an integer or undef
Check if the attribute is any of the listed types (think union). Takes a list of types as the argument, for example:
isa => AnyOf[Int, ArrayRef[Int], HashRef[Int]]
Note: AnyOf is passed an ArrayRef[CodeRef]
Check if the attribute is all of the listed types (think intersection) Takes a list of types as the argument. For example:
isa => AllOf[ InstanceOf['Human'], ConsumerOf['Air'], HasMethods['breath', 'dance'] ],
In addition, we have some parameterized types that take string arguments.
Check if the attribute is an object instance of one or more classes. Uses blessed and isa to do so. Takes a list of class names as the argument. For example:
blessed
isa
isa => InstanceOf['MyClass','MyOtherClass']
Note: InstanceOf is passed an ArrayRef[Str]
Check if the attribute is blessed and consumes one or more roles. Uses blessed and does to do so. Takes a list of role names as the arguments. For example:
does
isa => ConsumerOf['My::Role', 'My::AnotherRole']
Check if the attribute is blessed and has one or more methods. Uses blessed and can to do so. Takes a list of method names as the arguments. For example:
can
isa => HasMethods[qw/postulate contemplate liberate/]
Check if the attribute is one of the enumerated strings. Takes a list of possible string values. For example:
isa => Enum['rock', 'spock', 'paper', 'lizard', 'scissors']
