AbstractHierarchicalFileConfiguration
abstract public class AbstractHierarchicalFileConfiguration extends HierarchicalConfiguration implements FileConfiguration,ConfigurationListener(Code)

Base class for implementing file based hierarchical configurations.

This class serves an analogous purpose as the AbstractFileConfiguration class for non hierarchical configurations. It behaves in exactly the same way, so please refer to the documentation of AbstractFileConfiguration for further details.
