code to iterate Document Library for feature

Question

I'm writing a timer job that needs to email document owners when a document column (review Date=today) I want features to be available in sites which I can activate site collection.

How do I ensure that the site where I activate the feature is the site that gets iterated. I've done this in the past but used absolute url's

i.e. SPSite site = webApplication.Sites[http];

However I dont want to give any specific urls as I want one feature available on numerous sites in a single site collection.

Could someone help with method to use and getting a reference for the site where activated and iterating list in that site pls? I found the following pieces of code:

public override void Execute(Guid contentDbId)
 {
 // 1 here }

or

public override void Execute(Guid targetInstanceId)

{
 // 2 here }

Code found to iterate a list https://stackoverflow.com/questions/965695/iterate-a-sharepoint-list

public override void FeatureActivated(SPFeatureReceiverProperties properties)
 {
     using(SPSite site = properties.Feature.Parent as SPSite)
     {
         SPList list = site.RootWeb.Lists["ListName"];
         SPListItemCollection items = list.Items;

        foreach (SPListItem listItem in items)
         {
             Response.Write(SPEncode.HtmlEncode(listItem["Url"].ToString()) +"
");
         }
     }
 }

I also have a feature in the project (can this be used to gather the path of activated site?

 public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            SPSite site = properties.Feature.Parent as SPSite;

            // make sure the job isn't already registered

            foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)
            {
                if (job.Name == List_JOB_NAME1)
                    job.Delete();
            }

            // install the job

            ReviewDocument ListTimerJob1 = new ReviewDocument("ReviewDate", site.WebApplication);
}

Answer 1

You could create a second Site scoped feature that sets a SPSite.Properties value which tells the timer job that it can work on that specific site collection.

Then your application scoped timer job can iterate through all site collections recursively until it finds a site collection with that flag on it.
