Moose::Meta::Class - The Moose metaclass
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.
Moose::Meta::Class is a subclass of Class::MOP::Class.
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.
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 => [...] );
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.
This overrides the parent's method in order to add support for attribute triggers.
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.
This adds an override method modifier to the package.
This adds an augment method modifier to the package.
This will return a unique array of Moose::Meta::Role instances which are attached to this class.
This will return a unique array of Moose::Meta::Role instances which are attached to this class, and each of this class's ancestors.
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.
Returns a list of Moose::Meta::Role::Application::ToClass objects, which contain the arguments to role 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.
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.
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.
This overrides the parent's method in order to allow the parameters to be provided as a hash reference.
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.
