Result

サマリー

A Result object is returned by geoprocessing tools.

説明

The advantage of a Result object is that you can maintain information about the execution of tools, including messages, parameters, and output. These results can be maintained even after several other tools have been run.

構文

 Result  (toolname, resultID)

パラメーター	説明	データ タイプ
toolname	The name of the executed tool.	String
resultID	The job ID.	Integer

プロパティ

プロパティ	説明	データ タイプ
inputCount (読み取り専用)	Returns the number of inputs.	Integer
maxSeverity (読み取り専用)	Returns the maximum severity of the messages. 0 —If the tool produced only informative messages. 1 — If the tool produced a warning message, but no error messages. 2 — If the tool produced an error message.	Integer
messageCount (読み取り専用)	Returns the number of messages.	Integer
outputCount (読み取り専用)	Returns the number of outputs.	Integer
resultID (読み取り専用)	Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "".	String
status (読み取り専用)	Gets the job status. 0 —New 1 —Submitted 2 —Waiting 3 —Executing 4 —Succeeded 5 —Failed 6 —Timed out 7 —Cancelling 8 —Cancelled 9 —Deleting 10 —Deleted	Integer

方法の概要

方法	説明
cancel ()	Cancels an associated job
getInput (index)	Returns a given input, either as a recordset or string.
getMapImageURL ({parameter_list}, {height}, {width}, {resolution})	Returns a map service image for a given output, if one exists.
getMessage (index)	Returns a specific message by index position.
getMessages ({severity})	Returns the geoprocessing tool messages.
getOutput (index)	Returns a given output, either as a string or a RecordSet. If the output of the tool, such as Make Feature Layer, is a layer, getOutput will return a Layer object.
getSeverity (index)	Returns the severity of a specific message.
saveToFile (rlt_file)	Saves the result to a result file. 注意: saveToFile is not supported in ArcGIS Pro; use the Package Result tool instead.

方法

cancel ()

getInput (index)

パラメーター	説明	データ タイプ
index	The index position of the input.	Integer

戻り値

データ タイプ	説明
Object	The input, either as a recordset or string.

getMapImageURL ({parameter_list}, {height}, {width}, {resolution})

パラメーター	説明	データ タイプ
parameter_list	The parameters on which the map service image will be based.	Integer
height	The height of the image.	Double
width	The width of the image.	Double
resolution	The resolution of the image.	Double

戻り値

データ タイプ	説明
String	The URL of the map image.

getMessage (index)

パラメーター	説明	データ タイプ
index	The index position of the message.	Integer

戻り値

データ タイプ	説明
String	The geoprocessing message.

getMessages ({severity})

パラメーター	説明	データ タイプ
severity	The type of messages to be returned. 0 —Informative, warning, and error messages are returned. 1 —Only warning messages are returned. 2 —Only error messages are returned. Not specifying a severity level will return all types of messages. (デフォルト値は次のとおりです 0)	Integer

戻り値

データ タイプ	説明
String	The geoprocessing tool messages.

getOutput (index)

パラメーター	説明	データ タイプ
index	The index position of the outputs.	Integer

戻り値

データ タイプ	説明
Object	The output, either as a recordset or a string. If the output of the tool, such as Make Feature Layer, is a layer, getOutput will return a Layer object. Result outputs can also be accessed by index, so result.getOutput(0) and result[0] are equivalent.

getSeverity (index)

パラメーター	説明	データ タイプ
index	The message index position.	Integer

戻り値

データ タイプ	説明
Integer	The severity of the specific message. 0 —Informative, warning, and error messages are returned. 1 —Only warning messages are returned. 2 —Only error messages are returned.

saveToFile (rlt_file)

パラメーター	説明	データ タイプ
rlt_file	Full path to the output result file (.rlt).	String

コードのサンプル

Result example 1

Use the result object returned from GetCount to determine the count of a table.

import arcpy

in_table = arcpy.GetParameterAsText(0)
result = arcpy.GetCount_management(in_table)
print(result[0])

Result example 2

Obtain the feature set schema from the server tool, load data to the feature set, pass the feature set to the server tool, and check for the result object. Once completed, save the result to the local dataset.

import time
import arcpy

# Add a toolbox from a server
arcpy.ImportToolbox("http://myserver/arcgis/services;GP/BufferByVal",
                    "servertools")

# Use GetParameterValue to get a featureset object with the default
# schema of the first parameter of the tool 'bufferpoints'
in_featureset = arcpy.GetParameterValue("bufferpoints", 0)

# Load a shapefile into the featureset
in_featureset.load("C:/Data/roads.shp")

# Run a server tool named BufferPoints with featureset created above
result = arcpy.BufferPoints_server(in_featureset, "500 feet")

# Check the status of the result object every 0.2 seconds
#    until it has a value of 4 (succeeded) or greater
while result.status < 4:
    time.sleep(0.2)

# Get the output FeatureSet back from the server and save to a local geodatabase
out_featureset = result.getOutput(0)
out_featureset.save("c:/temp/base.gdb/roads_buffer")

Result example 3

Re-create the original geoprocessing service output using the tool name and result id.

import arcpy

# Add the toolbox from the server
arcpy.ImportToolbox("http://myserver/arcgis/services;GP/BufferByVal")

# Recreate the original output using the tool name and result id
result_id = 'jfea96e13ba7b443cb04ba47c19899a1b'
result = arcpy.Result("BufferPoints", result_id)
