Result

Zusammenfassung

A Result object is returned by geoprocessing tools.

Auswertung

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

Methodenübersicht

MethodeErklärung
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.

Hinweis:

saveToFile is not supported in ArcGIS Pro; use the Package Result tool instead.

String

The geoprocessing message.

getMessages ({severity})
ParameterErklärungDatentyp
severity

The type of messages to be returned: 0=message, 1=warning, 2=error. Not specifying a value returns all message types.

  • 0informational message
  • 1warning message
  • 2error message

(Der Standardwert ist 0)

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)
ParameterErklärungDatentyp
index

The message index position.

Integer

Codebeispiel

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)
