Examples of hudson.lifecycle.Lifecycle

hudson.lifecycle.Lifecycle
Provides the capability for starting/stopping/restarting/uninstalling Hudson.
The steps to perform these operations depend on how Hudson is launched, so the concrete instance of this method (which is VM-wide singleton) is discovered by looking up a FQCN from the system property "hudson.lifecycle". @author Kohsuke Kawaguchi @since 1.254
