cls
. If cls
is
an interface or an abstract class whose abstract methods follow the
JavaBeans convention, this method will create a concrete implementation
according to the metadata that defines the class. If cls
is a non-final concrete type that has metadata but does not implement
PersistenceCapable
, this method will
create a subclass of the type that does implement
PersistenceCapable
, and will attempt
to redefine the methods in cls
to enable persistent
attribute tracking. Otherwise, this will return an instance of the
specified class.
