protected abstract static class HierarchicalConfiguration.BuilderVisitor extends HierarchicalConfiguration.NodeVisitor
load()
method is
responsible 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 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.Modifier | Constructor and Description |
