        printObject=true,
        deferChildren=true)
public class LlapWrappedAppender
extends org.apache.logging.log4j.core.appender.AbstractAppender

An appender to wrap around RandomAccessFileAppender, and rename the file once the appender is closed. Could be potentially extended to other appenders by special casing them to figure out how files are to be handled.
