    • LinkResolver

      public LinkResolver(String id, Area a)
      Create a new link resolver.

      a - the area that will have the link attribute

  • Method Details

    • isResolved

      public boolean isResolved()
      Description copied from interface: Resolvable
      Check if this area has been resolved.
      Specified by:
      isResolved in interface Resolvable
      Returns:
      true if this link is resolved

    • getIDRefs

      public String[] getIDRefs()
      Get the references for this link.
      Specified by:
      getIDRefs in interface Resolvable
      Returns:
      the String array of references.

    • resolveIDRef

      public void resolveIDRef(String id, List<PageViewport> pages)
      Resolve by adding an internal link to the first PageViewport in the list. This method allows the Resolvable object to resolve one of its unresolved idrefs with the actual set of PageViewports containing the target ID. The Resolvable object initially identifies to the AreaTreeHandler which idrefs it needs resolved. After the idrefs are resolved, the ATH calls this method to allow the Resolvable object to update itself with the PageViewport information.
      Specified by:
      resolveIDRef in interface Resolvable
      Parameters:
      id - an ID matching one of the Resolvable object's unresolved idref's.
      pages - the list of PageViewports with the given ID

    • resolveIDRef

      public void resolveIDRef(String id, PageViewport pv)
      Resolve by adding an InternalLink trait to the area
      Parameters:
      id - the target id (should be equal to the object's idRef)
      pv - the PageViewport containing the first area with the given id

    • addDependent

      public void addDependent(Resolvable dependent)
      Add dependent resolvable. Used to resolve second-order resolvables that depend on resolution of this resolver.
      Parameters:
      dependent - resolvable
