## Annotation Type CommandLine.ParentCommand

-     @Retention(value=RUNTIME)
       @Target(value=FIELD)
      public static @interface CommandLine.ParentCommand

  Fields annotated with `@ParentCommand` will be initialized with the parent command of the current subcommand. If the current command does not have a parent command, this annotation has no effect.

  Parent commands often define options that apply to all the subcommands. This annotation offers a convenient way to inject a reference to the parent command into a subcommand, so the subcommand can access its parent options. For example:

       @Command(name = "top", subcommands = Sub.class)
       class Top implements Runnable {

           @Option(names = {"-d", "--directory"}, description = "this option applies to all subcommands")
           File baseDirectory;

           public void run() { System.out.println("Hello from top"); }
       }

       @Command(name = "sub")
       class Sub implements Runnable {

           @ParentCommand
           private Top parent;

           public void run() {
               System.out.println("Subcommand: parent command 'directory' is " + parent.baseDirectory);
           }
       }
