NAME¶
Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing
VERSION¶
version 2.0603
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!
