Relation Cache - Scope

In this video we discuss the scope of Cache for a relation and how to extend it

public class DemoCache : BusinessProcessBase
{
  public DemoCache()
  {
    Entities.Add(new Models.Shippers());
  }
  protected override void OnStart()
  {
    for (int i=0; i < 10; i++)
    {
-     new Child().Run();
      Cached<Child>().Run();
    }
    Exit();
  }
  public class Child : BusinessProcessBase
  {
    Models.Shippers Shippers = new Models.Shippers()
    {
      Cache = true
      , KeepCacheAliveAfterExit = true
    }
  }
} 

Steps:

1. Replace new with Cached on the call.
2. Add KeepCacheAliveAfterExit = true to the Entities you want to cache
3. Add the entity that you want to cache - to the parent controller you want to cache it in using Entities.Add

• It doesn't have to be the direct parent, it can be 1 ore more levels up in the stack (grand parent etc...)
• If the entity is already in use in the parent (in a From or a Relations.Add) , you don't need to add it again
