All Implemented Interfaces:

Serializable, IRI, Resource, URI, Value, MemResource, MemValue
```
public class MemIRI
extends Object
implements IRI, MemResource
```
A MemoryStore-specific implementation of URI that stores separated namespace and local name information to enable reuse of namespace String objects (reducing memory usage) and that gives it node properties.
