Result

Zusammenfassung

The result of a geoprocessing tool.

Diskussion

A Result object maintains information about a tool operation after it has completed. This includes messages, parameters, and outputs. Functions such as arcpy.GetMessages provide information solely from the preceding tool. However, you can maintain a Result object even after running other tools.

Syntax

 Result  (toolname, resultID)
ParameterErläuterungDatentyp
toolname

The name of the executed tool.

String
resultID

The job ID.

MethodeErläuterung
cancel ()

Cancels an associated job

getAllMessages ()

Returns the message types, return codes, and message strings.

getInput (index)

Returns a given input, either as a string or a RecordSet object.

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 RecordSet object or a string.

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.

DatentypErläuterung
List

Returns a list of lists that includes by position: the type, return code, and message string.

The first item in each internal list is an integer representing the message type.

  • 0Informative message
  • 1Definition message
  • 2Start message
  • 3Stop message
  • 50Warning message
  • 100Error message
  • 101Empty message
  • 102Geodatabase error message
  • 200Abort message

The second item is an integer representing the message return code. If the message has an associated ID number, the item will be ID number. Error messages that do not have an ID will return -2147467259. All other messages will return a 0. The second item is the message string.

getInput (index)
ParameterErläuterungDatentyp
index

The index position of the input as an integer, or the parameter name.

Variant

ParameterErläuterungDatentyp
parameter_list

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

Integer
height

The height of the image.

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.

The geoprocessing tool messages.

getOutput (index)
ParameterErläuterungDatentyp
index

The index position of the output as an integer, or the parameter name.

Variant

DatentypErläuterung
Variant

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 by integer or by name. For example, to access the record count from the Get Count tool, result.getOutput(0), result[0], result.getOutput("row_count"), and result["row_count"] are equivalent.

Codebeispiel

Result example 1

From a Result object returned from the Get Count tool, access the record count by index.

import arcpy

in_table = arcpy.GetParameterAsText(0)
result = arcpy.management.GetCount(in_table)
print(result[0])
Result example 2

From a Result object returned from the Get Count tool, access the record count by name.

import arcpy

in_table = arcpy.GetParameterAsText(0)
result = arcpy.management.GetCount(in_table)
print(result["row_count"])
Result example 3

The script obtains the feature set schema from a server tool, then loads data to the feature set, and passes it to the server tool. Once the tool completes, the script saves the result to a 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.server.BufferPoints(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 4

Re-create the output of a geoprocessing service 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)
