Index (arcpy)
摘要
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.
讨论
Index objects cannot be created directly. Index objects can accessed through the ListIndexes and Describe functions.
