```
public SafeMemory sharedCopy()
```
    Specified by:
    
    sharedCopy in interface SharedCloseable
    
    Returns:
    
    a new instance of the object representing the same state and backed by the same underlying resources. Coordinates with the original (and other instances) when the underlying resource should be closed. Throws an exception if the shared resource has already been closed.
