Summary
Provides the source, snap type, and search query information about the classes that are used to determine the network locations.
Discussion
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.
Properties
Property | Explanation | Data Type |
sourceX (Read Only) | The name of a particular class used by the locator. | String |
snapTypeX (Read Only) | An underscore-separated string containing the snap types used for a given class in the locator. The possible snap types are
| String |
searchQueryX (Read Only) | A query to restrict the search to a subset of the features within a given class in the locator. | String |
Code sample
Network Analyst Locator example
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)
