NAME¶
Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values.
VERSION¶
version 2.0603
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!
