CreateScratchName (arcpy)

摘要

为指定的数据类型创建唯一的临时路径名称。如果未给定工作空间，则使用当前工作空间。

语法

CreateScratchName ({prefix}, {suffix}, {data_type}, {workspace})

参数	说明	数据类型
prefix	The prefix that is added to the scratchname. By default, a prefix of xx is used. (默认值为 xx)	String
suffix	The suffix added to the scratchname. This can be an empty double-quoted string.	String
data_type	The data type which will be used to create the scratchname. Valid datatypes are: Coverage —Only valid Coverage names are returned. Dataset —Only valid Dataset names are returned. FeatureClass —Only valid FeatureClass names are returned. FeatureDataset —Only valid FeatureDataset names are returned. Folder —Only valid Folder names are returned. Geodataset —Only valid Geodataset names are returned. GeometricNetwork —Only valid Geometric Network names are returned. ArcInfoTable —Only valid ArcInfo Table names are returned. NetworkDataset —Only valid Network Dataset names are returned. RasterBand —Only valid Raster Band names are returned. RasterCatalog —Only valid Raster Catalog names are returned. RasterDataset —Only valid Raster Dataset names are returned. Shapefile —Only valid Shapefile names are returned. Terrain —Only valid Terrain names are returned. Workspace —Only valid Workspace scratchnames are returned.	String
workspace	The workspace used to determine the scratch name to be created. If not specified, the current workspace is used.	String

返回值

数据类型	说明
String	唯一的临时路径名称。

代码实例

CreateScratchName 示例

为“缓冲区”工具的派生输出创建唯一的临时路径。此路径名称将用作“裁剪”工具的输入。

import arcpy

# Set workspace
#
arcpy.env.workspace = "C:/Data/Municipal.gdb"

# Create a scratch name for the Buffer tool output.
#   The scratch name created will be include 'temp0.shp',
#   If temp0.shp already exists, the number will be incremented
#   until the name is unique in the workspace.
#
scratch_name = arcpy.CreateScratchName("temp",
                                       data_type="Shapefile",
                                       workspace=arcpy.env.scratchFolder)

# Execute Buffer tool, using scratch name for output
#
arcpy.Buffer_analysis("Roads", scratch_name, "1000 feet")

# Execute Clip tool, using scratch name for input
#
arcpy.Clip_analysis(scratch_name, "CityBoundary", "CityRoads")

# Delete scratch dataset
arcpy.Delete_management(scratch_name)
