Result

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

Result (toolname, resultID)

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)	Renvoie le nombre d'entrées.	Integer
maxSeverity (Lecture seule)	Renvoie la gravité maximale du message.	Integer
messageCount (Lecture seule)	Renvoie le nombre de messages.	Integer
outputCount (Lecture seule)	Renvoie le nombre de sorties.	Integer
resultID (Lecture seule)	Obtient l'ID de tâche. Si l'outil n'est pas un service de géotraitement, la propriété resultID est "".	String
status (Lecture seule)	Obtient l'état de la tâche. 0 —Nouveau 1 —Envoyé 2 —Attente 3 —Exécution 4 —Réussie 5 —Echec 6 —Délai d'attente dépassé 7 —Annulation 8 —Annulé 9 —Suppression 10 —Supprimé	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.
getSeverity (index)	Returns the severity of a specific message.

Méthodes

cancel ()

getInput (index)

Paramètre	Explication	Type de données
index	The index position of the input.	Integer

Valeur renvoyée

Type de données	Explication
Object	The input, either as a recordset or string.

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

Paramètre	Explication	Type de données
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

Valeur renvoyée

Type de données	Explication
String	The URL of the map image.

getMessage (index)

Paramètre	Explication	Type de données
index	The index position of the message.	Integer

Valeur renvoyée

Type de données	Explication
String	The geoprocessing message.

getMessages ({severity})

Paramètre	Explication	Type de données
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 (La valeur par défaut est 0)	Integer

Valeur renvoyée

Type de données	Explication
String	The geoprocessing messages.

getOutput (index)

Paramètre	Explication	Type de données
index	The index position of the outputs.	Integer

Valeur renvoyée

Type de données	Explication
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)

Paramètre	Explication	Type de données
index	The message index position.	Integer

Valeur renvoyée

Type de données	Explication
Integer	The severity of the specific message. 0 —informational message 1 —warning message 2 —error message

Exemple de code

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)
