      • findSelection

        public org.eclipse.jface.viewers.IStructuredSelection findSelection​(org.eclipse.ui.IEditorInput editorInput)

        This implementation uses the input element provider to convert the given editor input to an IElement (the input element). It then attempts to obtain the current selection in the navigator view and returns it unchanged if the currently selected element could be adapted to an IElement and the adapter element is a descendant of the input element. Otherwise, it returns a structured selection containing a single object, the input element. If no IElement could be provided for the editor input, this implementation attempts to adapt the editor input to an IFile and returns a structured selection consisting of that file. If all else fails, null is returned.

        Specified by:
        findSelection in interface org.eclipse.ui.navigator.ILinkHelper
      • activateEditor

        public void activateEditor​(org.eclipse.ui.IWorkbenchPage page,
                                   org.eclipse.jface.viewers.IStructuredSelection selection)

        This implementation does nothing if the given selection is null or empty or contains two or more elements. Otherwise, it uses the editor utility to find the editor for the selected element and to reveal the element in the editor.
