NAME
Moose::Meta::Class - The Moose metaclass
VERSION
version 2.2200
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.
