Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`begin()`	Positions this iterator at the first range of leaf cells (if any).
`void`	`next()`	Advances the iterator to the next range of leaf cells.
`boolean`	`prev()`	Returns false if the iterator was already positioned at the beginning, otherwise positions the iterator at the previous entry and returns true.
`void`	`seek(S2CellId target)`	Positions the iterator at the range containing "target".

  - seek
```
public void seek(S2CellId target)
```
    Description copied from class: S2CellIndex.RangeIterator
    
    Positions the iterator at the range containing "target". Such a range exists as long as the target is a valid leaf cell.
    
    Overrides:
    
    seek in class S2CellIndex.RangeIterator
    
    Parameters:
    
    target - a valid leaf (level 30) cell to seek to
