Zusammenfassung
Provides the source, snap type, and search query information about the classes that are used to determine the network locations.
Auswertung
The source, snapType, and searchQuery properties for the locator object are dynamic. This means that the total number of properties supported by a given locator object depends on the locatorCount property. For example, if the value of the locatorCount property is 2, then the locator object will support source0, source1, snapType0, snapType1, searchQuery0, and seacrhQuery1 properties.

Displays the Network Analyst Layer Locator properties.
# Name: NALayerLocatorProperties_ex01.py
# Description: Prints the source name and snap type information
# for the locators used by a network analysis layer
import arcpy
in_layer = "C:/Data/Route.lyr"
# Create a Describe object from layer file.
desc = arcpy.Describe(in_layer)
count = desc.locatorCount
locators = desc.locators
#print locator information
print "Total Locators: ", count
for i in range(0, count):
sourceName = getattr(locators,"source" + str(i))
snapType = getattr(locators,"snapType" + str(i))
query = getattr(locators, "searchQuery" + str(i))
print "%s : %s : %s" % (sourceName,snapType, query)
