/**
|
|
* Utility class representing links to different views of a record
|
|
* for CMS authors, usually for {@link SiteTree} objects with "stage" and "live" links.
|
|
* Useful both in the CMS and alongside the page template (for logged in authors).
|
|
* The class can be used for any {@link DataObject} subclass implementing the {@link CMSPreviewable} interface.
|
|
*
|
|
* New item types can be defined by extending the {@link SilverStripeNavigatorItem} class,
|
|
* for example the "cmsworkflow" module defines a new "future state" item with a date selector
|
|
* to view embargoed data at a future point in time. So the item doesn't always have to be a simple link.
