Hi,
I updated JavaDoc and made a pull request that is now added to the others I did in the last

> Traverses the xpath and returns a Pointer. A Pointer provides easy access to a property.
If the xpath matches no properties in the graph, the pointer will be null.

> This is not true because not {{null}} is returned but {{NullPointer}}. This makes a tremendous
difference.
