Summary
Provides information about edge sources in a network dataset.
Properties
Property | Explanation | Data Type |
name (Read Only) | The name of the feature class associated with this network source. | String |
sourceID (Read Only) | The unique identifier of this network source within the network dataset. | Integer |
sourceType (Read Only) |
The type of network source. This property returns the following keywords:
| String |
elementType (Read Only) |
Network element type of the network source. This property returns the following keywords:
| String |
fromElevationFieldName (Read Only) | The field name in the feature class associated with the given edge feature source that is used as the from elevation field when determining connectivity at coincident end vertices. | String |
toElevationFieldName (Read Only) | The field name in the feature class associated with the given edge feature source that is used as the to elevation field when determining connectivity at coincident end vertices. | String |
connectivityPolicies (Read Only) | The network dataset edge Connectivity Policies object. This object can be used to determine connectivity information, such as connectivity policies and connectivity groups, used by the edge sources of the network dataset. | Object |
sourceDirections (Read Only) | The Network Source Directions object. This object can be used to determine directions properties specific to a particular edge source. The sourceDirections property is available only if the network dataset supports directions which can be determined using the supportsDirections property. | Object |
Code sample
Edge Source Properties example
Displays information for edge sources in a network dataset.
# Name: NDSAttributeProperties_ex01.py
# Description: Print the information about edge sources defined for the
# network dataset
import arcpy
import sys
# Set workspace
arcpy.env.workspace = "C:/Data/Paris.gdb/Transportation"
# Create a Describe object from the network dataset
desc = arcpy.Describe("ParisMultimodal_ND")
justify = 35
print ("------- Edge sources")
# Get all the edge sources for the network dataset
edgeSources = desc.edgeSources
if not edgeSources:
print " %*s" % (justify, "(No edge sources)")
sys.exit(0)
for edgeSource in edgeSources:
print (" %*s: %s" % (justify, "Source Name" , edgeSource.name))
