Class UpdateStatementsTask

  • All Implemented Interfaces:
    SearchIndexerImpl.Task, Runnable
    public class UpdateStatementsTask
extends Object
implements SearchIndexerImpl.Task
    Receive a collection of statements that have been added to the model, or delete from it. Find the URIs of search documents that may have been affected by these changes, and update those documents. ------------------- It would be nice to stream this whole thing, finding the URIs affected by each statement and updating those documents before proceding. However, it is very common for several statements within a group to affect the same document, so that method would result in rebuilding the document several times. Instead, we final all of the URIs affected by all statements, store them in a Set to remove duplicates, and then process the URIs in the set.
