      • 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.
