Edge Source Properties

摘要

Provides information about edge sources in a network dataset.

属性

属性	说明	数据类型
name （只读）	The name of the feature class associated with this network source.	String
sourceID （只读）	The unique identifier of this network source within the network dataset.	Integer
sourceType （只读）	The type of network source. This property returns the following keywords: EdgeFeature JunctionFeature SystemJunction TurnFeature NetworkSource	String
elementType （只读）	Network element type of the network source. This property returns the following keywords: Edge Junction Turn	String
fromElevationFieldName （只读）	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 （只读）	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 （只读）	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 （只读）	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

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))
    print (" %*s: %s" % (justify, "Source ID" , str(edgeSource.sourceID))) 
    print (" %*s: %s" % (justify, "Source Type", edgeSource.sourceType))
    print (" %*s: %s" % (justify, "Element Type", edgeSource.elementType))
    print (" %*s: %s" % (justify, "From Elevation Field",
                         edgeSource.fromElevationFieldName))
    print (" %*s: %s" % (justify, "To Elevation Field",
                         edgeSource.toElevationFieldName))
    print(" ")
