  • Constructor Details

    • SQLTableLoadDialog

      public SQLTableLoadDialog()
      Constructor.

  • Method Details

    • isAvailable

      public boolean isAvailable()
      Description copied from class: AbstractTableLoadDialog
      The default implementation returns true.
      Specified by:
      isAvailable in interface TableLoadDialog
      Overrides:
      isAvailable in class AbstractTableLoadDialog
      Returns:
      true iff this dialogue may be able to do something useful

    • configure

      public void configure(StarTableFactory tfact, Action submitAct)
      Description copied from interface: TableLoadDialog
      Provides some configuration which must be performed before use. This method should be called before TableLoadDialog.getQueryComponent() is called.

      The tfact argument provides a table factory which resembles the one to be used for generating tables. Although this factory should not in general be used or retained, since the one presented later to the TableLoader should be used instead, it can be interrogated for known table formats etc.

      The submitAct argument sets the action which when invoked will cause TableLoadDialog.createTableLoader() to be called. Its setEnabled method can be called to reflect readiness, and it can be added as a listener to dialogue-specific events which indicate that a selection has been made.

      Specified by:
      configure in interface TableLoadDialog
      Overrides:
      configure in class AbstractTableLoadDialog
      Parameters:
      tfact - representative table factory
      submitAct - action for load submission

    • createQueryComponent

      protected Component createQueryComponent()
      Description copied from class: AbstractTableLoadDialog
      Constructs the query component used by this dialogue. Called only once (lazily).
      Specified by:
      createQueryComponent in class AbstractTableLoadDialog
      Returns:
      query component

    • createTableLoader

      public TableLoader createTableLoader()
      Description copied from interface: TableLoadDialog
      Returns a new object which specifies how table loading is to be performed. The actions performed by the returned object will presumably be determined by the state at call time of this dialogues GUI component.

      If the dialogue is not in a suitable state, either return null, or, if you want to provide more detailed information about what's wrong, throw a RuntimeException with an informative message.

      Returns:
      new table loader object
