Provides access to members that create a temporary spatial index for improving performance of "Disjoint" and some other relational operators. Note: the ISpatialIndex interface has been superseded byISpatialIndex2. Please consider using the more recent version.
The ISpatialIndex methods can be used to control whether or not a spatial index should be built and used for the IRelationalOperator operations. It also determines if an index should be built when getting an segment enumerators using ISegmentCollection::IndexedEnumSegments method.
