Result (arcpy)
Récapitulatif
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.
Syntaxe
Paramètre | Explication | Type de données |
toolname |
The name of the executed tool. | String |
resultID |
The job ID. | Integer |
Propriétés
Propriété | Explication | Type de données |
inputCount (Lecture seule) |
Returns the number of inputs. | Integer |
maxSeverity (Lecture seule) |
Returns the maximum severity of the messages.
| Integer |
messageCount (Lecture seule) |
Returns the number of messages. | Integer |
outputCount (Lecture seule) |
Returns the number of outputs. | Integer |

Vue d'ensemble des méthodes
Méthode | Explication |
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. |

Exemple de code
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)
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")
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)
