.TH Perl::Critic::PolicyParameter::Behavior::Enumeration 3pm "2020-05-17" "perl v5.30.0" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.

.SH "NAME"
Perl::Critic::PolicyParameter::Behavior::Enumeration \- Actions appropriate for an enumerated value.
.SH "DESCRIPTION"
.IX Header "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.
.PP
\&\s-1NOTE:\s0 Do not instantiate this class.  Use the singleton instance held
onto by
Perl::Critic::PolicyParameter.
.SH "INTERFACE SUPPORT"
.IX Header "INTERFACE SUPPORT"
This is considered to be a non-public class.  Its interface is subject
to change without notice.
.SH "METHODS"
.IX Header "METHODS"
.ie n .IP """initialize_parameter( $parameter, $specification )""" 4
.el .IP "\f(CWinitialize_parameter( $parameter, $specification )\fR" 4
.IX Item "initialize_parameter( $parameter, $specification )"
Plug in the functionality this behavior provides into the parameter,
based upon the configuration provided by the specification.
.Sp
This behavior looks for two configuration items:
.RS 4
.IP "enumeration_values" 4
.IX Item "enumeration_values"
Mandatory.  The set of valid values for the parameter, as an array
reference.
.IP "enumeration_allow_multiple_values" 4
.IX Item "enumeration_allow_multiple_values"
Optional, defaults to false.  Should the parameter support a single
value or accept multiple?
.RE
.RS 4
.RE
.ie n .IP """generate_parameter_description( $parameter )""" 4
.el .IP "\f(CWgenerate_parameter_description( $parameter )\fR" 4
.IX Item "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.
.Sp
In this specific case, the universe of values is added at the end.
