摘要
以下属性是在公共设施网络中使用 Describe 时由 nearestAssets 对象返回的。
如果使用过滤器 nearest 函数进行追踪操作,则这些是将要返回的资产组和资产类型。
属性
属性 | 说明 | 数据类型 |
assetGroupCode (只读) | 资产组代码。 | Integer |
assetTypeCode (只读) | 资产类型代码。 | Integer |
networkSourceID (只读) | 网络源的 ID。 | Integer |
代码示例
以下独立 Python 脚本可打印某些公共设施网络属性的报告。
# Import required modules
import arcpy
# Describe functions on a Utility Network
UN = "C:\\Projects\\MyProject\\unowner.sde\\Naperville.UNOWNER.Naperville\\Naperville.UNOWNER.Naperville"
d = arcpy.Describe(UN)
# Domain Network properties
domnets = d.domainNetworks
# For each domain network in the utility network
for dom in domnets:
print(f"Domain Network Name: {dom.domainNetworkName}")
# For each tier in the domain network
for tier in dom.tiers:
print(f"Tier Name: {tier.name}")
# Update Subnetwork Trace Configuration Properties
ust = tier.updateSubnetworkTraceConfiguration
# Nearest Neighbor Properties
print(" - Nearest Neighbor Properties - ")
nn = ust.nearestNeighbor
# Try to get these properties if the exist, else, print the empty list
try:
print(f"Count: {nn.count}")
print(f"Cost Network Attribute Name: {nn.costNetworkAttributeName}")
print(f"Nearest Categories: {nn.nearestCategories} \n")
