public abstract class AttributeContainer

extends java.lang.Object

Base class for XFP entities that contain attributes.

XFP attributes are a subset of Avalon components. Currently only a small subset of the Avalon Framework is supported. The supported interfaces are:

• org.apache.avalon.framework.parameters.Parameterizable
• org.apache.avalon.framework.activity.Initializable
• org.apache.avalon.framework.activity.Startable
• org.apache.avalon.framework.activity.Disposable

I need someone with a better knowledge of Avalon to improve this. Please help!
