Specio::Constraint::ObjectDoes - A class for constraints which require an object that does a specific role
version 0.12
my $type = Specio::Constraint::ObjectDoes->new(...); print $type->role();
This is a specialized type constraint class for types which require an object that does a specific role.
This class provides all of the same methods as Specio::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, role. This must be a single role name.
role
Returns the role name passed to the constructor.
This class does the Specio::Constraint::Role::DoesType, Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
