Table 6.244 — DRM_Spatial_Index_Data

Property

Description

Class
  • <DRM Spatial Index Data>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class specifies the (1-based) row and column indices of a cell within a regular spatial relationship of cells. <DRM Spatial Index Data> instances are used within spatial-index-related organizations to distinguish sibling branches of the organizations.

Given the origin of the spatial-index-related organization instance, and the row and column widths defined by that organization instance, the location of any cell is easily determined from its <DRM Spatial Index Data>.
