org.apache.commons.configuration2.BaseHierarchicalConfiguration
A specialized visitor base class that can be used for storing the tree of configuration nodes. The basic idea is that each node can be associated with a reference object. This reference object has a concrete meaning in a derived class, e.g. an entry in a JNDI context or an XML element. When the configuration tree is set up, the {@code load()} method isresponsible for setting the reference objects. When the configuration tree is later modified, new nodes do not have a defined reference object. This visitor class processes all nodes and finds the ones without a defined reference object. For those nodes the {@code insert()}method is called, which must be defined in concrete sub classes. This method can perform all steps to integrate the new node into the original structure.
