          public org.eclipse.ui.IViewPart openView(org.eclipse.ui.IWorkbenchPage page,
                                                   java.lang.Object[] inputElements)
                                            throws org.eclipse.ui.PartInitException

      Shows a call hierarchy view in the given workbench page, gives it focus, and sets its input to the given elements. If there is no 'unpinned' call hierarchy view in the given page, a new instance of the view is created; otherwise, the most recently activated 'unpinned' view is reused.

      Parameters:
        `page` - not `null`
        `inputElements` - not `null`, must not contain nulls; may be empty
      Returns:
        the opened view (never `null`)
      Throws:
        `org.eclipse.ui.PartInitException` - if the view could not be initialized
        `java.lang.IllegalArgumentException` - if the given elements are not valid input elements for the view
