Avalon Framework API 4.3.1 · org.apache.avalon.framework.configuration

Component configuration interfaces and XML-based implementations.

The org.apache.avalon.framework.configuration package contains primarily:

The Configurable interface, which a Component implements if it needs to be configured with externally-specified data before it is initialized.
The Configuration interface, an implementation of which will be passed to Components that implement Configurable.
The Reconfigurable interface, which Components implement if they need to be reconfigured at runtime.
Various classes providing the default XML-based implementation of Configuration. The mapping from XML to Configuration tree is described in DefaultConfigurationBuilder.
