Class LockedModel

java.lang.Object

edu.cornell.mannlib.vitro.webapp.rdfservice.adapters.AbstractModelDecorator

edu.cornell.mannlib.vitro.webapp.utils.jena.criticalsection.LockedModel

All Implemented Interfaces:

AutoCloseable, org.apache.jena.rdf.model.Model, org.apache.jena.rdf.model.ModelCon, org.apache.jena.rdf.model.ModelGraphInterface, org.apache.jena.rdf.model.RDFReaderF, org.apache.jena.rdf.model.RDFWriterF, org.apache.jena.shared.Lock, org.apache.jena.shared.PrefixMapping

public class LockedModel
extends AbstractModelDecorator
implements AutoCloseable

A model that is easy to use in a try-with-resources code block. It can only be created by locking a LockableModel.

 try (LockedModel m = lockableModel.read()) {
    ...
 }
 

The close method has been hijacked to simply release the lock, and not to actually close the wrapped model.
