Query of persistent storage
---------------------------
Key: QI-2
URL: http://issues.ops4j.org/jira/browse/QI-2
Project: Qi4j
Issue Type: New Feature
Reporter: Niclas Hedhman
Assignee: Rickard Öberg
Priority: Critical
We need the ability to query for composites.
public interface CompositeQueryFactory
{
CompositeQuery newQuery( String language )
throws UnknownQueryLanguageException; // UnkownQuer....Exception is
runtime exception.
}
public interface CompositeQuery
{
Iterator<PersistentComposite> query( String expression )
throws IOException
}
The indexing subsystem for a query language should also provide a
DependencyResolver for a CompositeQuery, so that
public class MyMixin
{
@Dependency("SPARQL") CompositeQuery query;
}
