Type::Constraint::AnyCan - A class for constraints which require a class name or object with a set of methods
version 0.02
my $type = Type::Constraint::AnyCan->new(...); print $_, "\n" for @{ $type->methods() };
This is a specialized type constraint class for types which require a class name or object with a defined set of methods.
This class provides all of the same methods as Type::Constraint::Simple, with a few differences:
The parent parameter is ignored if it passed, as it is always set to the Defined type.
parent
Defined
The inline_generator and constraint parameters are also ignored. This class provides its own default inline generator subroutine reference.
inline_generator
constraint
This class overrides the message_generator default if none is provided.
message_generator
Finally, this class requires an additional parameter, methods. This must be an array reference of method names which the constraint requires. You can also pass a single string and it will be converted to an array reference internally.
methods
Returns an array reference containing the methods this constraint requires.
This class does the Type::Constraint::Role::CanType, Type::Constraint::Role::Interface, Type::Role::Inlinable, and MooseX::Clone roles.
