      int getSelectionCount()
      Returns the number of objects in this selection.
      Returns:
      the number of objects in this ILcdSelection.

    • selectedObjects

      Enumeration<T> selectedObjects()
      Returns the objects in this selection.
      Returns:
      the objects currently in this ILcdSelection.

    • isSelected

      boolean isSelected(Object aObject)
      Checks whether the given Object is currently in the set of selected objects.
      Parameters:
      aObject - the Object to be checked.

    • addSelectionListener

      void addSelectionListener(ILcdSelectionListener<T> aSelectionListener)
      Adds a listener to this selection. In case you need to register a listener which keeps a reference to an object with a shorter life-time than this ILcdSelection, you can use a ALcdWeakSelectionListener instance as selection listener.
      Parameters:
      aSelectionListener - the ILcdSelectionListener to be added.

    • removeSelectionListener

      void removeSelectionListener(ILcdSelectionListener<T> aSelectionListener)
      Removes an ILcdSelectionListener from this ILcdSelection.
      Parameters:
      aSelectionListener - the ILcdSelectionListener to be removed.
