Hi all,
I have a requirement where my object needs a dependancy to a service. In
this case I want to gritter a notification message.
There are some design solutions:
* notify via an event
* inject a dependancy during a load from the database
* Use a unit of work to publish a notification message
Here are some examples.
== Notify via an event ==
class MyEntity
{
public static event Reset ...;
public static OnReset()
{
if(Reset!=null) Reset(this, null);
}
}
MyEntity.Reset += ()=> Bus.Publish(new ResetMessage());
var entity = Session.Get<MyEntity>();
entity.Reset();
== Inject dependancy to publish event ==
class MyEntity
{
public IBus Bus { get; set; }
public void Reset()
{
Bus.Publish(new ResetMessage());
}
}
== Use a unit of work to publish a notification message ==
var entity = Session.Get<MyEntity>();
entity.Reset();
Bus.Publish(new ResetMessage());
Does anybody have any experience with one of these solutions? I am
especially interested in if the second example (inject a dependancy during a
load/get from the database) is possible with NHiberate. I think it is
because it can use Castle Windsor but I do not know how I can pass the
container that contains the dependancies.
