How to Remember the State in Eclipse e4

In Eclipse 3.x we can easily know whether application is launching first time or it is restoring the state by checking method restoreState() in ApplicationWorkbenchAdvisor class, but this feature is not available in Eclipse 4.x, So can anyone help me how can I know whether the Eclipse state is restore or not in Eclipse 4?

You could set a value in the 'persisted state' of the application and check that during start up.

The earliest the application object is available is the @ProcessAdditions step of the LifeCyle class.

@ProcessAdditions
void processAdditions(MApplication app)
{
  String value = app.getPersistedState().get("myKey");

  if (value == null)  // Starting with nothing to restore
   {
     app.getPersistedState().put("myKey", "set");

     ...
   }
  else
   {
     ... persisted state exists
   }

}
