```
private Geometry get_result_geometry(int dim)
```
  - next
```
public Geometry next()
```
    Description copied from class: GeometryCursor
    
    Moves the cursor to the next Geometry. Returns null when reached the end. The behavior of the cursor is undefined after the method returns null.
    
    Specified by:
    
    next in class GeometryCursor
  - getGeometryID
```
public int getGeometryID()
```
    Description copied from class: GeometryCursor
    
    Returns the ID of the current geometry. The ID is propagated across the operations (when possible). Returns an ID associated with the current Geometry. The ID is passed along and is returned by some operators to preserve relationship between the input and output geometry classes. It is not always possible to preserve an ID during an operation.
    
    Specified by:
    
    getGeometryID in class GeometryCursor

                      boolean unioned,

```
  - tock
```
public boolean tock()
```
    Description copied from class: GeometryCursor
    
    Executes a unit of work on the cursor.
    
    Overrides:
    
    tock in class GeometryCursor
    
    Returns:
    
    Returns true, if there is a geometry ready to be pulled using next(). This method is to be used together with the tick() method on the ListeningGeometryCursor. Call tock() for each tick() on the ListeningGeometryCursor.
