                                  throws LinkException

Transforms a uuid to a handle beginning with a /. This path is used to get the page from the repository. The editor needs this kind of links.

Throws:

LinkException

convertUUIDtoURI

public static String convertUUIDtoURI(String uuid,
                                      String repository)
                               throws LinkException

Transforms a uuid to an uri. It does not add the context path. In difference from Link.getHandle(), this method will apply all uri to repository mappings as well as i18n.

Throws:

LinkException

convertAbsoluteLinksToUUIDs

public static String convertAbsoluteLinksToUUIDs(String html)
