# Interface: com.pnfsoftware.jeb.core.output.tree.INodeCoordinates

A coordinates system for nodes inside an [ITreeDocument](ITreeDocument). 

 The address is a path from the root to the node. Each element in a path is a zero\-indexed value that indicates the current parent position in the tree branch. 

 Example tree:  

```

 a
 b\>-+
 c  e
 d  f
    g
 
```
 

 Coordinates of: 
 
- a : \(0\)
-  
- b : \(1\)
-  
- e : \(1,0\)
-  
- f : \(1,1\)

## Method: getPath
- return type: `java.util.List<java.lang.Integer>`

Description: Return the path of the node being addressed. A path is a tuple of positions in each of the branch leading from the root to the node.
