NAME
Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing
VERSION
version 2.2203
DESCRIPTION
This class represents type constraints based on an enumerated list of
required methods.
INHERITANCE
"Moose::Meta::TypeConstraint::DuckType" is a subclass of
Moose::Meta::TypeConstraint.
METHODS
Moose::Meta::TypeConstraint::DuckType->new(%options)
This creates a new duck type constraint based on the given
%options.
It takes the same options as its parent, with several
exceptions. First, it requires an additional option, "methods". This
should be an array reference containing a list of required method
names. Second, it automatically sets the parent to the "Object" type.
Finally, it ignores any provided "constraint" option. The constraint
is generated automatically based on the provided "methods".
$constraint->methods
Returns the array reference of required methods 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::DuckType"
object!
