Moose::Meta::Class(3pm) User Contributed Perl Documentation Moose::Meta::Class(3pm)
NAME
Moose::Meta::Class - The Moose metaclass
VERSION
version 2.2012
DESCRIPTION
This class is a subclass of Class::MOP::Class that provides additional Moose-specific
functionality.
To really understand this class, you will need to start with the Class::MOP::Class
documentation. This class can be understood as a set of additional features on top of the
basic feature provided by that parent class.
INHERITANCE
"Moose::Meta::Class" is a subclass of Class::MOP::Class.
METHODS
Moose::Meta::Class->initialize($package_name, %options)
This overrides the parent's method in order to provide its own defaults for the
"attribute_metaclass", "instance_metaclass", and "method_metaclass" options.
These all default to the appropriate Moose class.
Moose::Meta::Class->create($package_name, %options)
This overrides the parent's method in order to accept a "roles" option. This should be
an array reference containing roles that the class does, each optionally followed by a
hashref of options ("-excludes" and "-alias").
my $metaclass = Moose::Meta::Class->create( 'New::Class', roles => [...] );
Moose::Meta::Class->create_anon_class
This overrides the parent's method to accept a "roles" option, just as "create" does.
It also accepts a "cache" option. If this is "true", then the anonymous class will be
cached based on its superclasses and roles. If an existing anonymous class in the
cache has the same superclasses and roles, it will be reused.
my $metaclass = Moose::Meta::Class->create_anon_class(
superclasses => ['Foo'],
roles => [qw/Some Roles Go Here/],
cache => 1,
);
Each entry in both the "superclasses" and the "roles" option can be followed by a hash
reference with arguments. The "superclasses" option can be supplied with a -version
option that ensures the loaded superclass satisfies the required version. The "role"
option also takes the "-version" as an argument, but the option hash reference can
also contain any other role relevant values like exclusions or parameterized role
arguments.
$metaclass->new_object(%params)
This overrides the parent's method in order to add support for attribute triggers.
$metaclass->superclasses(@superclasses)
This is the accessor allowing you to read or change the parents of the class.
Each superclass can be followed by a hash reference containing a -version value. If
the version requirement is not satisfied an error will be thrown.
When you pass classes to this method, we will attempt to load them if they are not
already loaded.
$metaclass->add_override_method_modifier($name, $sub)
This adds an "override" method modifier to the package.
$metaclass->add_augment_method_modifier($name, $sub)
This adds an "augment" method modifier to the package.
$metaclass->calculate_all_roles
This will return a unique array of Moose::Meta::Role instances which are attached to
this class.
$metaclass->calculate_all_roles_with_inheritance
This will return a unique array of Moose::Meta::Role instances which are attached to
this class, and each of this class's ancestors.
$metaclass->add_role($role)
This takes a Moose::Meta::Role object, and adds it to the class's list of roles. This
does not actually apply the role to the class.
$metaclass->role_applications
Returns a list of Moose::Meta::Role::Application::ToClass objects, which contain the
arguments to role application.
$metaclass->add_role_application($application)
This takes a Moose::Meta::Role::Application::ToClass object, and adds it to the
class's list of role applications. This does not actually apply any role to the class;
it is only for tracking role applications.
$metaclass->does_role($role)
This returns a boolean indicating whether or not the class does the specified role.
The role provided can be either a role name or a Moose::Meta::Role object. This tests
both the class and its parents.
$metaclass->excludes_role($role_name)
A class excludes a role if it has already composed a role which excludes the named
role. This tests both the class and its parents.
$metaclass->add_attribute($attr_name, %params|$params)
This overrides the parent's method in order to allow the parameters to be provided as
a hash reference.
$metaclass->constructor_class($class_name)
$metaclass->destructor_class($class_name)
These are the names of classes used when making a class immutable. These default to
Moose::Meta::Method::Constructor and Moose::Meta::Method::Destructor respectively.
These accessors are read-write, so you can use them to change the class name.
