org.apache.abdera.model.Link

Represents an Atom Link element.

Per RFC4287:

 The "atom:link" element defines a reference from an entry or feed to a Web resource.  This specification assigns no meaning to the content (if any) of this element. atomLink = element atom:link { atomCommonAttributes, attribute href { atomUri }, attribute rel { atomNCName | atomUri }?, attribute type { atomMediaType }?, attribute hreflang { atomLanguageTag }?, attribute title { text }?, attribute length { text }?, undefinedContent }

  public static InReplyTo addInReplyTo(Entry entry, Entry ref) {
    if (ref.equals(entry)) return null;
    InReplyTo irt = addInReplyTo(entry); 
    try {
      irt.setRef(ref.getId());
      Link altlink = ref.getAlternateLink();
      if (altlink != null) {
        irt.setHref(altlink.getResolvedHref());
        if (altlink.getMimeType() != null) 
          irt.setMimeType(altlink.getMimeType());
      }
      Source src = ref.getSource();
      if (src != null) {
        Link selflink = src.getSelfLink();
        if (selflink != null)
          irt.setSource(selflink.getResolvedHref());
      }
    } catch (Exception e) {}
    return irt;
