public class DefaultBeanFactory extends Object implements BeanFactory
The default implementation of the BeanFactory
interface.
This class creates beans of arbitrary types using reflection. Each time the
createBean()
method is invoked, a new bean instance is
created. A default bean class is not supported.
An instance of this factory class will be set as the default bean factory for
the
class. This means that if not bean
factory is specified in a BeanHelper
, this
default instance will be used.
