### Internal method
object (such as a typical C<< L<search|DBIx::Class::ResultSet/search>->
L<next|DBIx::Class::ResultSet/next> >> call) are actually Result
instances, based on your application's
-L<Result class|DBIx::Class::Manual::Glossary/Result_class>.
+L<Result Class|DBIx::Class::Manual::Glossary/Result Class>.
L<DBIx::Class::Row> implements most of the row-based communication with the
underlying storage, but a Result class B<should not inherit from it directly>.
Indicates whether the object exists as a row in the database or
not. This is set to true when L<DBIx::Class::ResultSet/find>,
-L<DBIx::Class::ResultSet/create> or L<DBIx::Class::ResultSet/insert>
-are used.
+L<DBIx::Class::ResultSet/create> or L<DBIx::Class::Row/insert>
+are invoked.
Creating a result object using L<DBIx::Class::ResultSet/new_result>, or
calling L</delete> on one, sets it to false.
