NAME
Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typingDESCRIPTION
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!
