Overview
This is a specialized type constraint class for types which require an object that does a specific role.
API
This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:
Specio::Constraint::ObjectDoes->new( ... )
The "parent" parameter is ignored if it passed, as it is always set to the "Defined" type.
The "inline_generator" and "constraint" parameters are also ignored. This class provides its own default inline generator subroutine reference.
This class overrides the "message_generator" default if none is provided.
Finally, this class requires an additional parameter, "role". This must be a single role name.
$object_isa->role
Returns the role name passed to the constructor.
Roles
This class does the Specio::Constraint::Role::DoesType, Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
