Resumen
A Result object is returned by geoprocessing tools.
Debate
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.
Sintaxis
Result (toolname, resultID)
Parámetro | Explicación | Tipo de datos |
toolname | The name of the executed tool. | String |
resultID | The job ID. | Integer |
Propiedades
Propiedad | Explicación | Tipo de datos |
inputCount (Sólo lectura) | Returns the number of inputs. | Integer |
maxSeverity (Sólo lectura) | Returns the maximum severity of the messages.
| Integer |
messageCount (Sólo lectura) | Returns the number of messages. | Integer |
outputCount (Sólo lectura) | Returns the number of outputs. | Integer |
resultID (Sólo lectura) | Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "". | String |
status (Sólo lectura) | Gets the job status.
| Integer |
Vista general del método
Método | Explicación |
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. |
Métodos
cancel ()
getInput (index)
Parámetro | Explicación | Tipo de datos |
index | The index position of the input. | Integer |
Valor de retorno
Tipo de datos | Explicación |
Object | The input, either as a recordset or string. |
getMapImageURL ({parameter_list}, {height}, {width}, {resolution})
Parámetro | Explicación | Tipo de datos |
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 |
Valor de retorno
Tipo de datos | Explicación |
String | The URL of the map image. |
getMessage (index)
Parámetro | Explicación | Tipo de datos |
index | The index position of the message. | Integer |
Valor de retorno
Tipo de datos | Explicación |
String | The geoprocessing message. |
getMessages ({severity})
Parámetro | Explicación | Tipo de datos |
severity | The type of messages to be returned: 0=message, 1=warning, 2=error. Not specifying a value returns all message types.
(El valor predeterminado es 0) | Integer |
Valor de retorno
Tipo de datos | Explicación |
String | The geoprocessing messages. |
getOutput (index)
Parámetro | Explicación | Tipo de datos |
index | The index position of the outputs. | Integer |
Valor de retorno
Tipo de datos | Explicación |
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)
Parámetro | Explicación | Tipo de datos |
index | The message index position. | Integer |
Valor de retorno
Tipo de datos | Explicación |
Integer | The severity of the specific message.
|
saveToFile (rlt_file)
Parámetro | Explicación | Tipo de datos |
rlt_file | Full path to the output result file (.rlt). | String |

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)
