com.foreach.across.modules.web.menu.Menu

Represents a hierarchical menu (tree) structure.

All items in the menu can be sorted using a Comparator, the same Comparator can be applied to all submenus in the tree. By default no comparator is attached and items will be sorted according to the natural order of their title.

Alternatively a Menu can be set as Ordered, in which case sorting will have no effect. The Ordered property must be set on all submenus separately, as it is not inherited. This means it is possible to provide an inheritable Comparator on the menu, but sort the menu itself manually and only use the Comparator for all submenus.

Note that sorting needs to be done explicitly, see {@link #sort()} method.

    assertMenu( menu.getItem( Menu.byPath( "/aaa" ) ).getItem( Menu.byPath( "333" ) ), "111", "222", "333" );
