How to update and maintain viewer state through different executions in eclipse RCP?

Question

I need to maintain viewer state in Eclipse even the eclipse project is closed. Also I need to update the viewer like if I am reloading it from eclipse menu.

Using viewer.refresh() just refreshes the tableviewer that I have inside it but it doesn't update it (re-running the code for filling the columns). I tried to use viewer.update(param1,param2) but I don't know what is param2, actually what is the right one. This update can be done manually by reloading the view from Window->Show view->Other. How can I done this programatically ?

如果要重置表中显示的数据，则必须使用要显示的数据再次调用TableViewer.setInput(xxx) 。
