Moose::Meta::Role::Attribute(3pm)
NAME
Moose::Meta::Role::Attribute - A Moose Attribute metaclass for Roles
DESCRIPTION
This class implements the API for attributes in roles. Attributes in
roles are more like attribute prototypes than full blown attributes.
While they are introspectable, they have very little behavior.
METHODS
This class provides the following methods:
- Moose::Meta::Role::Attribute->new(...)
- This method accepts all the options that would be passed to the
constructor for Moose::Meta::Attribute. - $attr->metaclass
$attr->is - Returns the option as passed to the constructor.
- $attr->associated_role
- Returns the Moose::Meta::Role to which this attribute belongs, if
any. - $attr->original_options
- Returns a hash reference of options passed to the constructor. This
is used when creating a Moose::Meta::Attribute object from this
object. - $attr->attach_to_role($role)
- Attaches the attribute to the given Moose::Meta::Role.
- $attr->attribute_for_class($metaclass)
- Given an attribute metaclass name, this method calls
"$metaclass->interpolate_class_and_new" to construct an attribute
object which can be added to a Moose::Meta::Class. - $attr->clone
- Creates a new object identical to the object on which the method is called.
- $attr->is_same_as($other_attr)
- Compares two role attributes and returns true if they are
identical. - In addition, this class implements all informational predicates
implements by Moose::Meta::Attribute (and Class::MOP::Attribute).
