getBreadcrumbNavigation

de.digitalcollections.model.api.view.BreadcrumbNavigation getBreadcrumbNavigation(java.util.UUID nodeUuid)

Build and return the breadcrumb navigation for the given node UUID

Parameters:

nodeUuid - the uuid of the node.

Returns:

BreadcrumbNavigation with labels in all available languages
