  • Constructor Details

    • TapServiceTreeModel

      protected TapServiceTreeModel(String rootLabel, TapServiceFinder.Service[] services, Map<TapServiceFinder.Service,TapServiceFinder.Table[]> tableMap)
      Constructor.
      Parameters:
      rootLabel - text label for root element (may be null)
      services - list of services nodes in tree
      tableMap - array of tables providing child nodes for each service; may be null if no table children are required, but if not null must contain an entry for each service

    • TapServiceTreeModel

      public TapServiceTreeModel(String rootLabel)
      Constructs an instance with no entries.
      Parameters:
      rootLabel - text label for root element (may be null)

  • Method Details

      public Object getRoot()
      Specified by:
      getRoot in interface TreeModel

    • isLeaf

      public boolean isLeaf(Object node)
      Specified by:
      isLeaf in interface TreeModel

    • getChildCount

      public int getChildCount(Object parent)
      Specified by:
      getChildCount in interface TreeModel

    • getChild

      public Object getChild(Object parent, int index)
      Specified by:
      getChild in interface TreeModel

    • getIndexOfChild

      public int getIndexOfChild(Object parent, Object child)
      Specified by:
      getIndexOfChild in interface TreeModel

    • valueForPathChanged

      public void valueForPathChanged(TreePath path, Object newValue)
      Specified by:
      valueForPathChanged in interface TreeModel

    • addTreeModelListener

      public void addTreeModelListener(TreeModelListener lnr)
      Specified by:
      addTreeModelListener in interface TreeModel

    • removeTreeModelListener

      public void removeTreeModelListener(TreeModelListener lnr)

    • getServicePath

      public static TreePath getServicePath(TreePath path)
      Returns a tree path which correponds to a TAP service, and which is an ancestor of the supplied path. The supplied path counts as its own ancestor for these purposes.
      Parameters:
      path - path to examine
      Returns:
      path corresponding to a sub-path of the supplied one, for which the terminal element is a TapServiceFinder.Service, or null if no service appears in the ancestry

    • getService

      public static TapServiceFinder.Service getService(TreePath path)
      Returns a service in the ancestry of a supplied path. The supplied path counts as its own ancestor for these purposes.
      Parameters:
      path - path to examine
      Returns:
      service owning the path, or null if no service appears in the ancestry

    • readTreeModel

      public static TapServiceTreeModel readTreeModel(TapServiceFinder.Service[] allServices, TapServiceFinder finder, TapServiceFinder.Constraint constraint) throws IOException
      Constructs a tree model based on some given constraints. May require a read of service data, hence should not be executed on the Event Dispatch Thread.
      Parameters:
      allServices - list of all services that may be relevant
      finder - object that can search for TAP services
      constraint - defines the services of interest; if null, all are used
      Returns:
      tree model
      Throws:
      IOException

    • createCellRenderer

      public static TreeCellRenderer createCellRenderer()
      Returns a cell renderer suitable for rendering nodes of a JTree using a model of this class.
      Returns:
      tree cell renderer
