Topic: TestTimer

[Jeff H]

This is a simple but useful idea from Lee Campbell's free ebook Introduction to Rx
 
Maybe should add logic for adding in Editor's EnteringQuiescentState event as pointed out by Spiderinnet1 at AutoCAD .NET: Real Performance of ObjectId.Open/GetObject Transaction and OpenCloseTransaction
 
Also adding logic for nesting might be useful?

Code - C#: [Select]

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Text;
5. using System.Diagnostics;
6. using Autodesk.AutoCAD.EditorInput;
7. using Autodesk.AutoCAD.ApplicationServices.Core;
8. namespace Autodesk.AutoCAD.Diagnostics
9. {

15.     public class TestTimer : IDisposable
16.     {
17.         private readonly string _name;
18.         private readonly Stopwatch _watch;
19.         public TestTimer(string name)
20.         {
21.             _name = name;
22.             _watch = Stopwatch.StartNew();
23.            
24.         }
25.         public void Dispose()
26.         {
27.             _watch.Stop();
28.             Application.DocumentManager.MdiActiveDocument.Editor.WriteLine("{0} took {1}", _name, _watch&#8204;.Elapsed);
29.         }
30.     }
31. }

Is useful something like this?

Code - C#: [Select]

1. public class TestTimer : IDisposable
2. {
3.         private readonly string _name;
4.         private readonly Stopwatch _watch;
5.         private readonly Action<string> _action;
6.        
7.         public TestTimer(string name)
8.         {
9.                 _name = name;
10.                 _watch = Stopwatch.StartNew();
11.         }
12.        
13.         public TestTimer(string name, Action<string> action)
14.                 : this(name)
15.         {
16.                 _action = action;
17.         }
18.        
19.         public void Dispose()
20.         {
21.                 _watch.Stop();
22.                 string message = string.Format("{0} took {1}", _name, _watch.Elapsed);
23.                 if (_action == null)
24.                         Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage("\n"+message);
25.                 else
26.                         _action(message);
27.         }
28. }

Code - C#: [Select]

1. using (TestTimer timer = new TestTimer("Creating 1000 random lines", n => log.AppendLine(n)))
2. {
3. ...
4. }

Yes Bargool that would be one way.
