- Method Detail
  - getGraphNodeId
```
int getGraphNodeId()
```
    A non-negative integer which serves as an identifier for this node in it's "dominant" graph. Initially this number is -1; a NumberedGraph will set it to a non-negative value when this node is inserted into the graph
    
    Returns:
    
    the identifier
  - setGraphNodeId
```
void setGraphNodeId(int number)
