NAME

Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values.

DESCRIPTION

This class represents type constraints based on an enumerated list of acceptable values.

INHERITANCE

Moose::Meta::TypeConstraint::Enum is a subclass of Moose::Meta::TypeConstraint.

METHODS

Moose::Meta::TypeConstraint::Enum->new(%options)

This creates a new enum type constraint based on the given %options.

It takes the same options as its parent, with several exceptions. First, it requires an additional option, values. This should be an array reference containing a list of valid string values. Second, it automatically sets the parent to the Str type.

Finally, it ignores any provided constraint option. The constraint is generated automatically based on the provided values.

$constraint->values

Returns the array reference of acceptable values provided to the constructor.

$constraint->create_child_type

This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

Note that it does not return a Moose::Meta::TypeConstraint::Enum object!

BUGS
