org.apache.commons.configuration2.io.FileHandler
An internal class that performs all update operations of the handler's {@code FileLocator} in a safe way even if there is concurrent access.This class implements anon-blocking algorithm for replacing the immutable {@code FileLocator} instance stored in an atomic reference by amanipulated instance. (If we already had lambdas, this could be done without a class in a more elegant way.)
