描述
为输入表的子类型设置默认值或默认编码。
使用方法
语法
SetDefaultSubtype(in_table, subtype_code)
参数 | 说明 | 数据类型 |
in_table | 要设置子类型默认值的输入表或要素类。 | Table View |
subtype_code | 子类型的唯一默认值。 | Long |
派生输出
名称 | 说明 | 数据类型 |
out_table | 已更新的表或要素类。 | 表视图 |
代码示例
以下 Python 窗口脚本演示了如何在即时模式下使用 SetDefaultSubtype 函数。
import arcpy
arcpy.env.workspace = "C:/data/Montgomery.gdb"
arcpy.SetDefaultSubtype_management("water/fittings", 5)
以下独立脚本演示了如何在将子类型添加到字段的工作流中使用 SetDefaultSubtype 函数。
#Name: ManageSubtypes.py
# Purpose: Create a subtype definition
# Import system modules
import arcpy
# Set the workspace (to avoid having to type in the full path to the data every time)
arcpy.env.workspace = "C:/data/Montgomery.gdb"
# Set local parameters
inFeatures = "water/fittings"
# Process: Set Subtype Field...
arcpy.SetSubtypeField_management(inFeatures, "TYPECODE")
# Process: Add Subtypes...
# Store all the suptype values in a dictionary with the subtype code as the "key" and the
# subtype description as the "value" (stypeDict[code])
stypeDict = {"0": "Unknown", "1": "Bend", "2": "Cap", "3": "Cross",
"4": "Coupling", "5": "Expansion joint", "6": "Offset", "7": "Plug",
"8": "Reducer", "9": "Saddle", "10": "Sleeve", "11": "Tap", "12": "Tee",
"13": "Weld", "14": "Riser"}
# Use a for loop to cycle through the dictionary
for code in stypeDict:
arcpy.AddSubtype_management(inFeatures, code, stypeDict[code])
# Process: Set Default Subtype...
arcpy.SetDefaultSubtype_management(inFeatures, "4")
