Namespace: CrawlerLib.Engine.Workflow
Assembly: CrawlerLib.Engine (in CrawlerLib.Engine.dll)

<Obfuscation(Exclude = true)> _
Public Class Delay
    Inherits ProcessableWorkflowChildBase


[Obfuscation(Exclude = true)]
public class Delay : ProcessableWorkflowChildBase


[Obfuscation(Exclude = true)]
public ref class Delay : public ProcessableWorkflowChildBase^


   Obfuscation(Exclude = true)
class Delay
   extends ProcessableWorkflowChildBase



This is the recommended mechanism to put a delay into a workflow.    Don't use Thread.Sleep() or any other blocking method to achieve delays.    This would block the execution threads of the Engine




 await new Delay(1000);


 new Delay(1000, delay => { /* Success Handler */} );
