| Name | Description | Type | Package | Framework |
| AbstractConfiguration | This is an abstract Configuration implementation that deals with methods that can be abstracted away from underlying implementations. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| Configurable | This interface should be implemented by classes that need to be configured with custom parameters before initialization. | Interface | org.apache.avalon.framework.configuration | Apache Avalon |
| Configuration | Configuration is a interface encapsulating a configuration node used to retrieve configuration values. | Interface | org.apache.avalon.framework.configuration | Apache Avalon |
| ConfigurationException | Thrown when a Configurable component cannot be configured properly, or if a value cannot be retrieved properly. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| ConfigurationUtil | This class has a bunch of utility methods to work with configuration objects. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| DefaultConfiguration | This is the default Configuration implementation. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| DefaultConfigurationBuilder | A DefaultConfigurationBuilder builds Configurations from XML, via a SAX2 compliant parser. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| DefaultConfigurationSerializer | A ConfigurationSerializer serializes configurations via SAX2 compliant parser. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| DefaultImmutableConfiguration | An immutable implementation of the Configuration interface. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| MutableConfiguration | A read/write extension of the Configuration interface. | Interface | org.apache.avalon.framework.configuration | Apache Avalon |
| NamespacedSAXConfigurationHandler | A SAXConfigurationHandler helps build Configurations out of sax events, including namespace information. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
| Reconfigurable | Interface | org.apache.avalon.framework.configuration | Apache Avalon | |
| SAXConfigurationHandler | A SAXConfigurationHandler helps build Configurations out of sax events. | Class | org.apache.avalon.framework.configuration | Apache Avalon |
