Table 6.252 — DRM_Spatial_Index_Data

Property

Description

Class

  • <DRM Spatial Index Data>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class specifies the row and column indexes of a cell within a regular spatial relationship of cells. <DRM 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 <DRM Spatial Index Data> link object.

The row_index field specifies the row within the spatial index related aggregation to which the specified cell belongs.

The column_index field specifies the column within the spatial index related aggregation to which the specified cell belongs.
