Class FileBoolean

java.lang.Object

jenkins.util.io.FileBoolean

public class FileBoolean
extends Object

Uses a presence/absence of a file as a persisted boolean storage.

This is convenient when you need to store just a few bits of infrequently accessed information as you can forget the explicit persistence of it. This class masks I/O problem, so if the persistence fails, you'll get no error report.
