FeatureSet

摘要

FeatureSet objects are a lightweight representation of a feature class. They are a special data element that contains not only schema, but also the data. The FeatureSet object is also how feature data is sent and received from the server.

FeatureSet example

Load data into FeatureSet and insert into feature class.

# Loading data to a FeatureSet using cursors 
#  and an in_memory feature class.
#
import arcpy
from arcpy import env

env.overwriteOutput = True

arcpy.ImportToolbox("http://flame7/arcgis/services;BufferByVal", "server")

# List of coordinates
#
coordinateL = ["-117.196717216;34.046944853","-117.186226483;34.046498438",
