RDFConnectionLocal (Apache Jena RDF Connection)

java.lang.Object
- org.apache.jena.rdfconnection.RDFConnectionLocal

All Implemented Interfaces:

AutoCloseable, RDFConnection, RDFDatasetAccessConnection, RDFDatasetConnection, SparqlQueryConnection, SparqlUpdateConnection, Transactional
```
public class RDFConnectionLocal
extends Object
implements RDFConnection
```
Implement of RDFConnection over a Dataset in the same JVM.
Multiple levels of Isolation are provided, The default COPY level makes a local RDFConnection behave like a remote connection. This should be the normal use in testing.
- COPY – Models and Datasets are copied. This is most like a remote connection.
- READONLY – Read-only wrappers are added but changes to the underlying model or dataset will be seen.
- NONE (default) – Changes to the returned Models or Datasets act on the original object.
