  • Method Details

    • get_result_geometry

      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
    • step_

      private boolean step_()
    • collect_geometries_to_union

      ArrayList<Geometry> collect_geometries_to_union(int dim)
    • remove_all_bins_with_lower_dimension

      private void remove_all_bins_with_lower_dimension(int dim)
    • add_geom

      private void add_geom(int dimension, boolean unioned, Geometry geom)
    • get_level_

      private static int get_level_(int sz)
    • get_vertex_count_

      private static int get_vertex_count_(Geometry geom)
    • 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.
