NAME¶
MooseX::Role::Parameterized::Meta::Trait::Parameterizable - trait for
parameterizable roles
VERSION¶
version 1.08
DESCRIPTION¶
This is the trait that is applied to the metaclass for parameterizable roles,
roles that have their parameters currently unbound. These are the roles that
you use "with" in Moose, but instead of composing the
parameterizable role, we construct a new parameterized role
(MooseX::Role::Parameterized::Meta::Role::Parameterized) and use that new
parameterized role instead.
ATTRIBUTES¶
The name of the class that will be used to construct the parameterized role.
parameters_class¶
The name of the class that will be used to construct the parameters object.
A metaclass representing this role's parameters. It will be an anonymous
subclass of "parameters_class". Each call to "parameter"
in MooseX::Role::Parameters adds an attribute to this metaclass.
When this role is consumed, the parameters object will be instantiated using
this metaclass.
role_generator¶
A code reference that is used to generate a role based on the parameters
provided by the consumer. The user usually specifies it using the
"role" in MooseX::Role::Parameterized keyword.
METHODS¶
add_parameter $name, %options¶
Delegates to "add_attribute" in Moose::Meta::Class on the
"parameters_metaclass" object.
construct_parameters %arguments¶
Creates a new MooseX::Role::Parameterized::Parameters object using metaclass
"parameters_metaclass".
The arguments are those specified by the consumer as parameter values.
generate_role %arguments¶
This method generates and returns a new instance of
"parameterized_role_metaclass". It can take any combination of three
named arguments:
- parameters
- A hashref of parameters for the role, same as would be passed in at a
"with" statement.
- package
- A package name that, if present, we will use for the generated role; if
not, we generate an anonymous role.
- consumer
- A consumer metaobject, if available.
apply¶
Overrides "apply" in Moose::Meta::Role to automatically generate the
parameterized role.
