Moose::Meta::TypeConstraint::Enum(3p)

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!
