Package org.apache.avalon.framework.configuration

Component configuration interfaces and XML-based implementations.

See: Description

Interface Summary

Interface	Description
Configurable	This interface should be implemented by classes that need to be configured with custom parameters before initialization.
Configuration	Configuration is a interface encapsulating a configuration node used to retrieve configuration values.
Reconfigurable	Extends Configurable to allow reconfiguration at runtime.

Exception Summary

Exception	Description
ConfigurationException	Thrown when a Configurable component cannot be configured properly, or if a value cannot be retrieved properly.

Package org.apache.avalon.framework.configuration Description

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.
