NAME

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

VERSION

version 2.1210

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!

See "BUGS" in Moose for details on reporting bugs.
