Result

Summary

The result of a geoprocessing tool.

Discussion

A Result object maintains information about a tool operation after it has completed. This includes messages, parameters, and outputs. Functions such as arcpy.GetMessages provide information solely from the preceding tool. However, you can maintain a Result object even after running other tools.

Syntax

 Result  (toolname, resultID)

Parameter	Explanation	Data Type
toolname	The name of the executed tool.	String
resultID	The job ID.	Integer

Properties

Property	Explanation	Data Type
inputCount (Read Only)	Returns the number of inputs.	Integer
maxSeverity (Read Only)	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 (Read Only)	Returns the number of messages.	Integer
outputCount (Read Only)	Returns the number of outputs.	Integer
resultID (Read Only)	Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "".	String

Method Overview

Method	Explanation
cancel ()	Cancels an associated job
getAllMessages ()	Returns the message types, return codes, and message strings.
getInput (index)	Returns a given input, either as a string or a RecordSet object.
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 RecordSet object or a string. 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.

Return Value

Data Type

Explanation

List

Returns a list of lists that includes by position: the type, return code, and message string. The first item in each internal list is an integer representing the message type. 0—Informative message 1—Definition message 2—Start message 3—Stop message 50—Warning message 100—Error message 101—Empty message 102—Geodatabase error message 200—Abort message The second item is an integer representing the message return code. If the message has an associated ID number, the item will be ID number. Error messages that do not have an ID will return -2147467259. All other messages will return a 0. The second item is the message string.

getInput (index)

Parameter	Explanation	Data Type
index	The index position of the input as an integer, or the parameter name.	Variant

Return Value

Data Type	Explanation
Variant	The input, either as a RecordSet object or a string.

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

Parameter	Explanation	Data Type
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

Return Value

Data Type	Explanation
String	The URL of the map image.

getMessage (index)

Parameter	Explanation	Data Type
index	The index position of the message.	Integer

Return Value

Data Type	Explanation
String	The geoprocessing message.

getMessages ({severity})

Parameter	Explanation	Data Type
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. (The default value is 0)	Integer

Return Value

Data Type	Explanation
String	The geoprocessing tool messages.

getOutput (index)

Parameter	Explanation	Data Type
index	The index position of the output as an integer, or the parameter name.	Variant

Return Value

Data Type	Explanation
Variant	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 by integer or by name. For example, to access the record count from the Get Count tool, result.getOutput(0), result[0], result.getOutput("row_count"), and result["row_count"] are equivalent.

getSeverity (index)

Parameter	Explanation	Data Type
index	The message index position.	Integer

Return Value

Data Type	Explanation
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)

Parameter	Explanation	Data Type
rlt_file	Full path to the output result file (.rlt).	String

Code sample

Result example 1

From a Result object returned from the Get Count tool, access the record count by index.

import arcpy

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

Result example 2

From a Result object returned from the Get Count tool, access the record count by name.

import arcpy

in_table = arcpy.GetParameterAsText(0)
result = arcpy.management.GetCount(in_table)
print(result["row_count"])

Result example 3

The script obtains the feature set schema from a server tool, then loads data to the feature set, and passes it to the server tool. Once the tool completes, the script saves the result to a 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.server.BufferPoints(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 4

Re-create the output of a geoprocessing service 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)
