    Parameters:
    
    depth - Level number of the QueryObject, to be used according to other arguments.
    
    changeValueGeneration - How to determine the values of the modified QueryObject. Can be one of : QueryObject.INCREMENT QueryObject.NEGATE
    
    delta - The number to increment or decrement; unused if changeValueGeneration is QueryObject.NEGATE.

```
    Creates new instance of the root QueryObject and modifies the values of the QueryObject at the given depth by changing its values according to changeValueGeneration and delta. In other words, the only new instance will be the top level QueryObject, but a deepter level QueryObject might be modified and it will not be a new instance. Since the top level QueryObject is a new instance, it could be used in a put to update a region entry.
    
    Parameters:
    
    changeValueGeneration - How to determine the values of the modified QueryObject. Can be one of : QueryObject.INCREMENT QueryObject.NEGATE
    
    delta - The number to increment or decrement; unused if changeValueGeneration is QueryObject.NEGATE.
    
    randomDepth - If true then modify a QueryObject at a randomly chosen depth between 1 and depth, if false then modify the QueryObject at the given depth.
    
    log - If true, then log what is being modified, if false don't log since output can be large.
  - depth
```
public int depth()
```
    Return the depth of the QueryObject.
  - getAtDepth
```
public QueryObject getAtDepth(int depth)
```
    Return the QueryObject at the given depth. For example, if depth is 1, then return this. If depth is 3, then return the QueryObject that is qo.aQueryObject.aQueryObject.
    
    Parameters:
    
    depth - The desired depth of the QueryObject.
    
    Returns:
