public void addRev ( String rev ) { Assert . hasLength ( rev ) ; linkParams . add ( REV . paramName , rev ) ; }
The rev parameter has been used in the past to indicate that the semantics of the relationship are in the reverse direction . That is a link from A to B with REL = X expresses the same relationship as a link from B to A with REV = X . rev is deprecated by this specification because it often confuses authors and readers ; in most cases using a separate relation type is preferable .
