Résumé
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) | 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 |
resultID (Lecture seule) | Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "". | String |
status (Lecture seule) | Gets the job status.
| 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}) | 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 string or a RecordSet. 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. Remarque :saveToFile is not supported in ArcGIS Pro; use the Package Result tool instead. |
Méthodes
cancel ()
getInput (index)
Paramètre | Explication | Type de données |
index | The index position of the input. | Integer |
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 | 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 |
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 |
Type de données | Explication |
String | The geoprocessing message. |
getMessages ({severity})
Paramètre | Explication | Type de données |
severity | The type of messages to be returned.
Not specifying a severity level will return all types of messages. (La valeur par défaut est 0) | Integer |
Type de données | Explication |
String | The geoprocessing tool messages. |
getOutput (index)
Paramètre | Explication | Type de données |
index | The index position of the outputs. | Integer |
Type de données | Explication |
Object | 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, so result.getOutput(0) and result[0] are equivalent. |
getSeverity (index)
Paramètre | Explication | Type de données |
index | The message index position. | Integer |
Type de données | Explication |
Integer | The severity of the specific message.
|
saveToFile (rlt_file)
Paramètre | Explication | Type de données |
rlt_file | Full path to the output result file (.rlt). | String |
Exemple de code
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])
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")
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)
