Ever felt the need to log what your ECO persistence server is up to?

Posted on April 14, 2011 by Admin
  1. public partial class ModelPMP : Eco.Persistence.PersistenceMapperProvider
  2. {
  3.     List<string> _log = new List<string>();
  4.     public ModelPMP() : base()
  5.     {
  6.       EcoListener.StartListening();
  7.       EcoLogSwitches.LogSql = true;
  8.       EcoListener.Singleton.OnTraceLog += new TraceLogHandler(OnTraceLog);
  9.       this.InitializeComponent();
  10.     }
  11.  
  12.     private void OnTraceLog(object sender, TraceEventArgs e)
  13.     {
  14.       if (e.Category.Equals(EcoTraceCategories.Sql))
  15.       {
  16.         _log.Add(e.Message);
  17.       }
  18.     }

The code above is one way…

To make an ExpressionHandle actually load all rows in as few batches as possible go like this:

  1. IObjectList il=(ehPerson.Element as IObjectList);
  2. il.EnsureObjects();

    Hello.
    Is it possible to use mentioned way to log changes for objects? For example, when I call UpdateDatabase() or CommitTransaction(), I need somehow to get old object, new object, compare them and if any changes log it.

    Thanks.
