Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing
version 2.1800
This class represents type constraints based on an enumerated list of required methods.
Moose::Meta::TypeConstraint::DuckType is a subclass of Moose::Meta::TypeConstraint.
Moose::Meta::TypeConstraint::DuckType
This creates a new duck type constraint based on the given %options.
%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.
methods
Object
Finally, it ignores any provided constraint option. The constraint is generated automatically based on the provided methods.
constraint
Returns the array reference of required methods provided to the constructor.
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!
