概要
A Result object is returned by geoprocessing tools.
ディスカッション
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.
構文
Result (toolname, resultID)
| パラメーター | 説明 | データ タイプ |
toolname | The name of the executed tool. | String |
resultID | The job ID. | Integer |
プロパティ
| プロパティ | 説明 | データ タイプ |
| inputCount (読み取り専用) | Returns the number of inputs. | Integer |
| maxSeverity (読み取り専用) | Returns the maximum severity of the messages.
| Integer |
| messageCount (読み取り専用) | Returns the number of messages. | Integer |
| outputCount (読み取り専用) | Returns the number of outputs. | Integer |
| resultID (読み取り専用) | Gets the job ID. If the tool is not a geoprocessing service, the resultID will be "". | String |
| status (読み取り専用) | Gets the job status.
| Integer |
手法の概要
| 手法 | 説明 |
| 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. |
手法
cancel ()
getInput (index)
| パラメーター | 説明 | データ タイプ |
index | The index position of the input. | Integer |
戻り値
| データ タイプ | 説明 |
| Object | The input, either as a recordset or string. |
getMapImageURL ({parameter_list}, {height}, {width}, {resolution})| パラメーター | 説明 | データ タイプ |
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 |
戻り値
| データ タイプ | 説明 |
| String | The URL of the map image. |
getMessage (index)
| パラメーター | 説明 | データ タイプ |
index | The index position of the message. | Integer |
戻り値
| データ タイプ | 説明 |
| String | The geoprocessing message. |
getMessages ({severity})| パラメーター | 説明 | データ タイプ |
severity | The type of messages to be returned: 0=message, 1=warning, 2=error. Not specifying a value returns all message types.
(デフォルト値は次のとおりです 0) | Integer |
戻り値
| データ タイプ | 説明 |
| String | The geoprocessing messages. |
getOutput (index)
| パラメーター | 説明 | データ タイプ |
index | The index position of the outputs. | Integer |
戻り値
| データ タイプ | 説明 |
| 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)
| パラメーター | 説明 | データ タイプ |
index | The message index position. | Integer |
戻り値
| データ タイプ | 説明 |
| Integer | The severity of the specific message.
|
saveToFile (rlt_file)
| パラメーター | 説明 | データ タイプ |
rlt_file | Full path to the output result file (.rlt). | String |
コードのサンプル
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)
