Result

Zusammenfassung

A Result object is returned by geoprocessing tools.

Diskussion

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

 Result  (toolname, resultID)
ParameterErläuterungDatentyp
toolname

The name of the executed tool.

resultID

The job ID.

Methodenübersicht

MethodeErläuterung
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.

Hinweis:

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

Methoden

ParameterErläuterungDatentyp
parameter_list

The parameters on which the map service image will be based.

Integer
height

The height of the image.

DatentypErläuterung
String

The URL of the map image.

getMessage (index)
ParameterErläuterungDatentyp
index

The index position of the message.

Integer
Rückgabewert
DatentypErläuterung
String

The geoprocessing message.

getMessages ({severity})
ParameterErläuterungDatentyp
severity

The type of messages to be returned.

  • 0Informative, warning, and error messages are returned.
  • 1Only warning messages are returned.
  • 2Only error messages are returned.

Not specifying a severity level will return all types of messages.

(Der Standardwert ist 0)

Integer
Rückgabewert
DatentypErläuterung
String

The geoprocessing tool messages.

getOutput (index)
ParameterErläuterungDatentyp
index

The index position of the outputs.

Integer
Rückgabewert
DatentypErläuterung
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)
ParameterErläuterungDatentyp
index

The message index position.

Integer
Rückgabewert
DatentypErläuterung
Integer

The severity of the specific message.

  • 0Informative, warning, and error messages are returned.
  • 1Only warning messages are returned.
  • 2Only error messages are returned.
saveToFile (rlt_file)
ParameterErläuterungDatentyp
rlt_file

Full path to the output result file (.rlt).

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)
