Result

Zusammenfassung

A Result object is returned by geoprocessing tools.

Beschreibung

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)
ParameterErläuterungDatentyp
toolname

The name of the executed tool.

String
resultID

The job ID.

Integer

Methodenübersicht

MethodeErläuterung
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.

Codebeispiel

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)
