org.apache.commons.configuration.tree.ReferenceNodeHandler

An extension of the {@link NodeHandler} interface which allows access toso-called references stored for a node.

Some specialized configuration implementations needs to store additional data for the nodes representing configuration properties. This interface provides methods for querying this data. For instance, it is possible to query a reference object stored for a specific node.

{@link InMemoryNodeModel} supports references. It can be queried for a{@code ReferenceNodeHandler} which can then be used for dealing withreferences.
