getBreadcrumbPart

public String getBreadcrumbPart()

Description copied from interface: OwBaseView

This method is used to create a "Breadcrumb" navigation view. The view is just attaching it's known title/name to the part which is returned from it child.

Example: We have a View A which contains a View B which has a many views contained.

      A.getBreadcrumbPart()
      {
          return this.getTitle() + " - " + B.getBreadcrumbPart();
      }
      B.getBreadcrumbPart()
      {
          return this.getName() + " - " + getMainView().getBreadcrumbPart();
      }
 

So every view is just returning the part of the navigation which is known in it's context. This method should not return null at least the OwBaseView.EMPTY_STRING should be returned.

Specified by:

getBreadcrumbPart in interface OwBaseView

Returns:

String representing the current bread crumb part
