NAME

Perl::Critic::PolicyParameter::Behavior::Enumeration - Actions appropriate for an enumerated value.

DESCRIPTION

Provides a standard set of functionality for an enumerated Perl::Critic::PolicyParameter so that the developer of a policy does not have to provide it her/himself.

NOTE: Do not instantiate this class. Use the singleton instance held onto by Perl::Critic::PolicyParameter.

INTERFACE SUPPORT

This is considered to be a non-public class. Its interface is subject to change without notice.

METHODS

"initialize_parameter( $parameter, $specification )": Plug in the functionality this behavior provides into the parameter, based upon the configuration provided by the specification.
This behavior looks for two configuration items:

enumeration_values: Mandatory. The set of valid values for the parameter, as an array reference.
enumeration_allow_multiple_values: Optional, defaults to false. Should the parameter support a single value or accept multiple?

"generate_parameter_description( $parameter )": Create a description of the parameter, based upon the description on the parameter itself, but enhancing it with information from this behavior.
In this specific case, the universe of values is added at the end.
