Examples of ImmutableNode

org.apache.commons.configuration.tree.ImmutableNode

An immutable default implementation for configuration nodes.

This class is used for an in-memory representation of hierarchical configuration data. It stores typical information like a node name, a value, child nodes, or attributes.

After their creation, instances cannot be manipulated. There are methods for updating properties, but these methods return new {@code ImmutableNode}instances. Instances are created using the nested {@code Builder} class.
