Result

Summary

A Result object is returned by geoprocessing tools.

Discussion

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.

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
status (Read Only)	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

Method Overview

Method	Explanation
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 a 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.
saveToFile (rlt_file)	Saves the result to a result file (.rlt).

Methods

cancel ()

getInput (index)

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

Return Value

Data Type	Explanation
Object	The input, either as a recordset or string.

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

Parameter	Explanation	Data Type
parameter_list	Parameter(s) 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=message, 1=warning, 2=error. Not specifying a value returns all message types. 0 —informational message 1 —warning message 2 —error message (The default value is 0)	Integer

Return Value

Data Type	Explanation
String	The geoprocessing messages.

getOutput (index)

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

Return Value

Data Type	Explanation
Object	The output, either as a recordset or a string. If the output of the tool, such as MakeFeatureLayer 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)

Parameter	Explanation	Data Type
index	The message index position.	Integer

Return Value

Data Type	Explanation
Integer	The severity of the specific message. 0 —informational message 1 —warning message 2 —error message

saveToFile (rlt_file)

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

Code sample

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)
