CreateObject
摘要
Creates geoprocessing objects. The extra arguments can be used to specify additional requirements for the object creation such as the number of columns in the ValueTable object.

注:
Instead of using CreateObject, consider using the equivalent ArcPy class. For instance, instead of arcpy.CreateObject("array"), use arcpy.Array().
语法
CreateObject (name, {options})
参数 | 说明 | 数据类型 |
name |
Name of the object to be created (ArcSDESQLExecute, Array, Extent, FeatureSet, Field, FieldInfo, FieldMap, FieldMappings, Geometry, NetCDFFileProperties, Point, RecordSet, Result, SpatialReference, ValueTable). | String |
options |
Optional argument(s) depend on the object being created. | Object |
数据类型 | 说明 |
Object |
The object returned depends on type of object specified in the first parameter. |
代码示例
CreateObject example
Use value table to hold feature class names and ranks for the Union tool.
import arcpy from arcpy import env # Set the workspace. List all of the feature classes in the dataset # env.workspace = "C:/Data/Landbase.gdb/Wetlands" fcs = arcpy.ListFeatureClasses() # Create the value table for the Analysis Union tool with 2 columns # vtab = arcpy.CreateObject("valuetable", 2) # Iterate through the list of feature classes # for fc in fcs: # Update the value table with a rank of 2 for each record, except # for BigBog # if fc.lower() != "bigbog": vtab.addRow(fc + " 2") else: vtab.addRow(fc + " 1") # Union the wetlands feature classes with the land use feature class to create # a single feature class with all of the wetlands and land use data # vtab.addRow("C:/Data/Landbase.gdb/land_use 2") arcpy.Union_analysis(vtab, "C:/Data/Landbase.gdb/wetlands_use")
