制图表达类属性 (arcpy)

摘要

Describe 函数可返回制图表达类的以下属性。同时还支持数据集属性。

可从 GDB 要素类的 GDBFeatureClass.representations 属性或 DescribeObject.children 属性获得制图表达类的 Describe 属性。

制图表达类可返回“RepresentationClass”的 dataType。

属性

属性	说明	数据类型
overrideFieldName (只读)	The name of the Override field.	String
requireShapeOverride (只读)	Indicates if a shape override is required for feature representations.	Boolean
ruleIDFieldName (只读)	The name of the RuleID field.	String

代码实例

RepresentationClass properties example (stand-alone script)

The following stand-alone script displays properties for all the representation classes in a feature class.

import arcpy

# Create a Describe object
#
desc = arcpy.Describe("C:/data/moad.gdb/Water_Bodies")

# Print RepresentationClass properties for each representation 
#   in the feature class.
#
for child in desc.representations:
    if child.datasetType == "RepresentationClass":
        print child.name
        print "\t%-25s %s" % ("Override field name:", child.overrideFieldName)
        print "\t%-25s %s" % ("Shape override required:", child.requireShapeOverride)
        print "\t%-25s %s" % ("RuleID field name:", child.ruleIDFieldName)
