Index (arcpy)

Récapitulatif

The Index object contains information about an index on a table. There are two types of indexes: spatial and attribute. Spatial indexes exist on the shape field of a feature class.

Discussion

Index objects cannot be created directly. Index objects can accessed through the ListIndexes and Describe functions.
