public interface ISpatialIndex
extends Serializable

Provides access to members that create a temporary spatial index for improving performance of "Disjoint" and some other relational operators.

ISpatialIndex2

Description

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.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

void	invalidate() Invalidate the spatial index.
boolean	isAllowIndexing() Indicates whether to allow a spatial index to be created for this geometry.
void	setAllowIndexing(boolean allowIndexing) Indicates whether to allow a spatial index to be created for this geometry.

Method Detail

setAllowIndexing

void setAllowIndexing(boolean allowIndexing)
                      throws IOException,
                             AutomationException

Indicates whether to allow a spatial index to be created for this geometry.

Remarks

The SpatialIndex if enabled is used by the IRelationalOperator's methods.

Product Availability
