Specio::Constraint::Enum(3pm) User Contributed Perl Documentation Specio::Constraint::Enum(3pm)

NAME

Specio::Constraint::Enum - A class for constraints which require a string matching one of a set of values

VERSION

version 0.48

SYNOPSIS

    my $type = Specio::Constraint::Enum->new(...);
    print $_, "\n" for @{ $type->values };

DESCRIPTION

This is a specialized type constraint class for types which require a string that matches one of a list of values.

API

This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:

Specio::Constraint::Enum->new( ... )

The "parent" parameter is ignored if it passed, as it is always set to the "Str" type.

The "inline_generator" and "constraint" parameters are also ignored. This class provides its own default inline generator subroutine reference.

Finally, this class requires an additional parameter, "values". This must be a an arrayref of valid strings for the type.

$enum->values

Returns an array reference of valid values for the type.

ROLES

This class does the Specio::Constraint::Role::Interface and Specio::Role::Inlinable roles.
