NAME
Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing
VERSION
version 2.2200
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!
