Result (arcpy)

サマリ

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

特性

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

メソッドの概要

メソッド	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})	Gets a map service image for a given output, if one exists.
getMessage (index)	Returns a specific message.
getMessages ({severity})	Returns messages.
getOutput (index)	Returns a given output, either as a recordset or string. If the output of the tool, such as MakeFeatureLayer is a layer, getOutput will return a Layer object.
getSeverity (index)	Returns the severity of a specific message.

メソッド

cancel ()

getInput (index)

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

getMessage (index)

パラメータ	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	説明	データ タイプ
severity	The type of messages to be returned: 0=message, 1=warning, 2=error. Not specifying a value returns all message types. 0 —informational message 1 —warning message 2 —error message (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 messages.

getOutput (index)

パラメータ	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 string. If the output of the tool, such as MakeFeatureLayer is a layer, getOutput will return a Layer object.

getSeverity (index)

パラメータ	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 —informational message 1 —warning message 2 —error message

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
inTable = arcpy.GetParameterAsText(0)
result = arcpy.GetCount_management(inTable)
print result.getOutput(0)

Result example 2

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

import arcpy
import time  

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

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

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

# Run a server tool named BufferPoints with featureset created above 
# 
result = arcpy.BufferPoints_server(inFeatureSet, "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 
# 
outFeatSet = result.getOutput(0)
outFeatSet.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)
