Class Name: Spatial Index Data

Superclass - <SEDRIS Abstract Base>

Subclasses

Definition

An instance of this DRM class specifies the row and column indexes of a cell within a regular spatial relationship of cells. <Spatial Index Data> link objects are used within spatial index related aggregations to distinguish sibling branches of the aggregations. The indexes for row and column are one-based.

Given the origin of the spatial index related aggregation and the row and column widths defined by that aggregation, the location of any cell is determined from its <Spatial Index Data> link object.
