public abstract class AbstractHierarchicalFileConfiguration extends HierarchicalConfiguration implements FileConfiguration, ConfigurationListener
Base class for implementing file based hierarchical configurations.
This class serves an analogous purpose as the
class for non hierarchical
configurations. It behaves in exactly the same way, so please refer to the
documentation of AbstractFileConfiguration
AbstractFileConfiguration
for further details.
