      NoSuchDataException

  • Method Details

    • 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

    • 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

    • 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

    • 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:
      "."

    • getPathElement

      public String getPathElement()
      Description copied from class: DefaultDataNode
      The DefaultDataNode implementation returns the label as a default path element.
      Specified by:

      Overrides:
      getPathElement in class DefaultDataNode
      Returns:
      the node's label
