  • Constructor Details

  • Method Details

    • getName

      public String getName()
      Description copied from interface: DataNode
      Gets the name of this object. This is an intrinsic property of the object.
      Specified by:
      getName in interface DataNode
      Overrides:
      getName in class DefaultDataNode
      Returns:
      the name of the object

    • getNodeTLA

      public String getNodeTLA()
      Description copied from class: DefaultDataNode
      The DefaultDataNode implementation returns the string "...".
      Specified by:
      getNodeTLA in interface DataNode
      Overrides:
      getNodeTLA in class DefaultDataNode
      Returns:
      "..."

    • getNodeType

      public String getNodeType()
      Description copied from interface: DataNode
      Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.
      Specified by:
      getNodeType in interface DataNode
      Overrides:
      getNodeType in class DefaultDataNode
      Returns:
      a short description of the type of this DataNode

    • getPathSeparator

      public String getPathSeparator()
      Description copied from class: DefaultDataNode
      Returns a default separator string.
      Specified by:
      getPathSeparator in interface DataNode
      Overrides:
      getPathSeparator in class DefaultDataNode
      Returns:
      "."

    • getParentObject

      public Object getParentObject()
      Description copied from interface: DataNode
      Returns an object which is in some sense the parent of the one this node is based on. The parent is not a DataNode, it is something which may get fed to a DataNodeFactory to create DataNode. If no such object exists, which may well be the case, null should be returned.
      Specified by:
      getParentObject in interface DataNode
      Overrides:
      getParentObject in class DefaultDataNode
      Returns:
      an object which is the parent of this one, or null

    • getDescription

      public String getDescription()
      Description copied from interface: DataNode
      Gets a concise description of this object. The form of the description will depend on the type of node, but it might detail the shape or type of data represented, or otherwise give some information additional to the name. It should not include the return value of the getName method, since they may be presented together. It should be on one line, and preferably no longer than around 70 characters. The null value may be returned if there is nothing to say.
      Specified by:
      getDescription in interface DataNode
      Overrides:
      getDescription in class DefaultDataNode
      Returns:
      a short string describing this object

    • getChildMaker

      public DataNodeFactory getChildMaker()
      Description copied from interface: DataNode
      Gets the factory which should in general be used to generate descendant nodes.
      Specified by:
      getChildMaker in interface DataNode
      Overrides:
      getChildMaker in class DefaultDataNode
      Returns:
      the factory used for generating children

    • allowsChildren

      public boolean allowsChildren()
      Description copied from class: DefaultDataNode
      The DefaultDataNode implementation of this method returns false.
      Specified by:
      allowsChildren in interface DataNode
      Overrides:
      allowsChildren in class DefaultDataNode
      Returns:
      true if the node is of a type which can have child nodes, false otherwise

    • getChildIterator

      public Iterator getChildIterator()
      Description copied from class: DefaultDataNode
      The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).
      Specified by:
      getChildIterator in interface DataNode
      Overrides:
      getChildIterator in class DefaultDataNode
      Returns:
      an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.

    • configureDetail

      public void configureDetail(DetailViewer dv)
      Description copied from class: DefaultDataNode
      No custom configuration is performed.
      Specified by:
      configureDetail in interface DataNode
      Overrides:
      configureDetail in class DefaultDataNode
      Parameters:
      dv - the detail viewer which this node is given an opportunity to configure

    • addVOComponentViews

      public static void addVOComponentViews(DetailViewer dv, uk.ac.starlink.votable.VOElement voel)

    • getSource

      public static DOMSource getSource(uk.ac.starlink.votable.VOElement voel)
      Returns a DOM source associated with a given VO Element.
      Parameters:
      voel - element
      Returns:
      source
