NAME¶
Moose::Meta::Role::Attribute - The Moose attribute metaclass for Roles
VERSION¶
version 2.0603
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_role
- Returns the Moose::Meta::Role in which this attribute was
first defined. This may not be the same as the value
"associated_role()" in the case of composite role, or the case
where one role consumes other roles.
- $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).
