java.lang.Object org.apache.commons.configuration.beanutils.DefaultBeanFactory org.apache.commons.configuration.DefaultConfigurationBuilder.ConfigurationProvider
A base class for creating and initializing configuration sources.
Concrete sub classes of this base class are responsible for creating
specific Configuration
objects for the tags in the
configuration definition file. The configuration factory will parse the
definition file and try to find a matching
ConfigurationProvider
for each encountered tag. This
provider is then asked to create a corresponding
Configuration
object. It is up to a concrete
implementation how this object is created and initialized.
Note that at the moment only configuration classes derived from
are supported.
