  extends the public category OrientGraphFactory ... {Public Boolean isLeveGraphsOpen () {return leaveGraphsOpen; } Open Public Zero Set Levegraph (Open Boolean Skip graph) {this.leaveGraphsOpen = leaveGraphsOpen; }}  

2) Why two public getDatabase () methods? For this, Graph Databases

The right way to do this is feeling pretty ugly: (
