                      Spatial filter)
```
- Method Detail
  - hasNext
```
public boolean hasNext()
```
    Specified by:
    
    hasNext in interface java.util.Iterator<V>
  - skip
```
public void skip(long n)
```
    Skip over that many entries. This method is relatively fast (for this map implementation) even if many entries need to be skipped.
    
    Parameters:
    
    n - the number of entries to skip
  - next
```
public Spatial next()
```
    Specified by:
    
    next in interface java.util.Iterator<V>
  - check
```
protected abstract boolean check(boolean leaf,
                                 Spatial key,
                                 Spatial test)
```
    Check a given key.
    
    Parameters:
    
    leaf - if the key is from a leaf page
    
    key - the stored key
    
    test - the user-supplied test key
    
    Returns:
    
    true if there is a match
