Result (arcpy)

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)

Parameter	Erläuterung	Datentyp
toolname	The name of the executed tool.	String
resultID	The job ID.	Integer

Eigenschaften

Eigenschaft	Erläuterung	Datentyp
inputCount (Schreibgeschützt)	Returns the number of inputs.	Integer
maxSeverity (Schreibgeschützt)	Returns the maximum severity of the messages. 0 —If the tool produced only informative messages. 1 — If the tool produced a warning message, but no error messages. 2 — If the tool produced an error message.	Integer
messageCount (Schreibgeschützt)	Returns the number of messages.	Integer
outputCount (Schreibgeschützt)	Returns the number of outputs.	Integer
resultID (Schreibgeschützt)	Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "".	String
status (Schreibgeschützt)	Gets the job status. 0 —New 1 —Submitted 2 —Waiting 3 —Executing 4 —Succeeded 5 —Failed 6 —Timed out 7 —Cancelling 8 —Cancelled 9 —Deleting 10 —Deleted	Integer

Methodenübersicht

Methode	Erläuterung
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 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.

getMessage (index)

Parameter	Erläuterung	Datentyp

Rückgabewert

Datentyp	Erläuterung
String	The geoprocessing message.

getMessages ({severity})

Parameter	Erläuterung	Datentyp
severity	The type of messages to be returned: 0=message, 1=warning, 2=error. Not specifying a value returns all message types. 0 —informational message 1 —warning message 2 —error message (Der Standardwert ist 0)	Integer

Rückgabewert

Datentyp	Erläuterung
Object	The output, either as a recordset or string. If the output of the tool, such as MakeFeatureLayer is a layer, getOutput will return a Layer object.

getSeverity (index)

Parameter	Erläuterung	Datentyp
index	The message index position.	Integer

Rückgabewert

Datentyp	Erläuterung
Integer	The severity of the specific message. 0 —informational message 1 —warning message 2 —error message

Codebeispiel

Result example 1

Use the result object returned from GetCount to determine the count of a table.

import arcpy
inTable = arcpy.GetParameterAsText(0)
result = arcpy.GetCount_management(inTable)
print result.getOutput(0)

Result example 2

Obtain feature set schema from server tool, load data to feature set, pass feature set to server tool, and check for result object. Once completed, save result to local dataset.

import arcpy
import time  

# Add a toolbox from a server 
#
arcpy.ImportToolbox("http://myserver/arcgis/services;GP/BufferByVal", "server") 

# Use GetParameterValue to get a featureset object with the default
#   schema of the first parameter of the tool 'bufferpoints' 
#
inFeatureSet = arcpy.GetParameterValue("bufferpoints", 0) 

# Load a shapefile into the featureset 
#
inFeatureSet.load("C:/Data/roads.shp") 

# Run a server tool named BufferPoints with featureset created above 
# 
result = arcpy.BufferPoints_server(inFeatureSet, "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 
# 
outFeatSet = result.getOutput(0)
outFeatSet.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)
