    Examine events

    Hello,

    Just porting some things across to V8. Can anyone tell me what the V8 equiv is of this code:

                    ExamineManager.Instance.IndexProviderCollection["ContentSearchIndexer"].GatheringNodeData
                 += (sender, e) => ExamineEvents.OnGatheringNodeData(sender, e);

            var indexer = (LuceneIndexer)ExamineManager.Instance.IndexProviderCollection["ContentSearchIndexer"];
            indexer.DocumentWriting += new EventHandler<Examine.LuceneEngine.DocumentWritingEventArgs>(ExamineEvents.Indexer_DocumentWriting);

    Thanks

    Hey Paul

    public class IndexerComponent : IComponent
{
    private readonly IExamineManager examineManager;
    public IndexerComponent(IExamineManager examineManager)
    {
           this.examineManager = examineManager;
    }

    public void Initialize()
    {
          var externalIndex = examineManager.Indexes.FirstOrDefault(i=>
                    i.Name.Equals("ExternalIndex");
         if(externalIndex != null)
         {
               ((BaseIndexProvider)externalIndex).TransformingIndexValues += ExternalTransformingIndexValues;
         }
    }

    public void Terminate(){}

    private void ExternalTransformingIndexValues(object sender, IndexingItemEventArgs e)
    {
            // Do Stuff here
    }
}

    Hope it helps,

    Nik

    Hi Nik,

    Thanks for this, I'll give it a go.

    In terms of whats changed for the OnGatheringNodeData, could you tell me how I access fields as before I could use e.Fields and loop through them, I cant seem to see this option anymore.

    Thanks

    Paul

    Hi Paul,

    Have a look at e.ValueSet.

    This is used in multiple ways:

    //This should get the ID of the node being indexed
e.ValueSet.Values["id"].FirstOrDefault()

//Adding a value
e.ValueSet.Add("FieldName", Value)

//Returns a collection of values for a field, for example a list of strings for tags
e.ValueSet.Values["fieldName"]

    Hope that helps

    Nik

    Thanks Nik, this is great - do you know how you remove a value - I used to use 

    e.Fields.Remove("Property")

    I can see Add, but can't see Remove anywhere.

    Thanks

    Paul

    I've not tried removing values, why are you trying to remove them?

    Can't remember exactly :) legacy code. I'll comment it out for now, see how it goes.

    I also have another function Indexer_DocumentWriting

                    var indexer = (LuceneIndexer)ExamineManager.Instance.IndexProviderCollection["ContentSearchIndexer"];
            indexer.DocumentWriting += new EventHandler<Examine.LuceneEngine.DocumentWritingEventArgs>(ExamineEvents.Indexer_DocumentWriting);

    Can you tell me what the equiv in v8 is for this? (Thanks for all your help by the way)

    Not sure there is, think they've all been pushed into that event. Ismail might have a better knowledge on this so could be worth reaching out to him.

    Twitter might be the best bet: https://twitter.com/ismailmayat or on Slack :-)
