org.apache.commons.configuration2.io.FileHandler

Definition of an interface to be implemented by {@link FileBased} objectswhich need access to the current {@link FileLocator}.

When loading or saving a {@code FileBased} object using {@code FileHandler}the handler eventually invokes the {@code read()} or {@code write()} methodspassing in a reader or writer. For some implementations this may not be sufficient because they need information about the current location. For instance, a concrete {@code FileBased} implementation may have to resolveother data sources based on relative file names which have to be interpreted in the context of the current file location.

To deal with such scenarios, affected implementations can choose to implement this interface. They are then passed the current location to the file being accessed before their {@code read()} or {@code write()} method is called.
