NAME

6       Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing
7

VERSION

DESCRIPTION

12       This class represents type constraints based on an enumerated list of
13       required methods.
14

INHERITANCE

16       "Moose::Meta::TypeConstraint::DuckType" is a subclass of
17       Moose::Meta::TypeConstraint.
18

METHODS

20   Moose::Meta::TypeConstraint::DuckType->new(%options)
21       This creates a new duck type constraint based on the given %options.
22
23       It takes the same options as its parent, with several exceptions.
24       First, it requires an additional option, "methods". This should be an
25       array reference containing a list of required method names. Second, it
26       automatically sets the parent to the "Object" type.
27
28       Finally, it ignores any provided "constraint" option. The constraint is
29       generated automatically based on the provided "methods".
30
31   $constraint->methods
32       Returns the array reference of required methods provided to the
33       constructor.
34
35   $constraint->create_child_type
36       This returns a new Moose::Meta::TypeConstraint object with the type as
37       its parent.
38
39       Note that it does not return a "Moose::Meta::TypeConstraint::DuckType"
40       object!
