Class AugurRepository

java.lang.Object
  org.openrdf.repository.base.RepositoryWrapper
      org.openrdf.repository.augur.AugurRepository

All Implemented Interfaces:

DelegatingRepository, Repository

public class AugurRepository
extends RepositoryWrapper

Wraps a Repository reducing traffic to the underlying repository for some requests. AugurRepository tags Resources leaving the Repository with the query that was used to retrieve it. When one of these resources is used as a binding to a new query it expands the new query to pro-actively retrieve the results for other resources with the same tag. This technique can change repository hits from O(n^m) into O(m) without changing how the data is accessed from the repository.
