Zusammenfassung
An object containing the results of a vehicle routing problem analysis that can be used to access outputs and solver messages.
Auswertung
Instances of this class cannot be created directly. Instead, they are returned by the solve method of the VehicleRoutingProblem class.
Eigenschaften
Eigenschaft | Erklärung | Datentyp |
isPartialSolution (Nur lesen) | Returns True if the solver produced a partial solution, meaning that not all inputs were included in the results. This can occur if one of the inputs is unlocated and the solver class's ignoreInvalidLocations property is set to True. | Boolean |
solveSucceeded (Nur lesen) | Returns True if the solve was successful. | Boolean |
Methodenübersicht
Methode | Erklärung |
count (output_type) | Returns the number of rows for an output type. |
export (output_type, output_features) | Exports the analysis results to a feature class or table. If the VehicleRoutingProblem object's returnStopShapes property is set to False, the exported output of VehicleRoutingProblemOutputDataType.Stops and VehicleRoutingProblemOutputDataType.UnassignedStops will be tables. If returnStopShapes is set to True, the exported output will be feature classes with geometry. |
fieldNames (output_type) | Returns a list of field names supported by a specified output type. |
saveAsLayerFile (file_name) | Saves the analysis result and settings to a layer file. The layer file can be opened in ArcGIS Desktop as a record of the analysis settings or to visualize the results. Layers produced from vehicle routing problem analyses cannot be opened in ArcGIS Pro. |
saveRouteData (file_name) | Save the outputs from the analysis to a .zip file. The .zip file can be used to share the routes from the analysis as route layer items in ArcGIS Online or ArcGIS Enterprise using the Share As Route Layers tool. Ein Routen-Layer-Element kann von verschiedenen Anwendungen verwendet werden, z. B. ArcGIS Navigator, um eine Routenführung für Außendienstmitarbeiter bereitzustellen, oder im Bereich Wegbeschreibung in Map Viewer, wo die im Routen-Layer enthaltene Route weiter angepasst werden kann. Alternativ können Sie mit ArcGIS Pro einen neuen Routenanalyse-Layer aus einem Routen-Layer erstellen. The output features will be created in the spatial reference of the network dataset used for analysis. If the arcpy.env.outputCoordinateSystem environment has been set, the output will be created in that spatial reference instead. If the solve fails, saveRouteData returns a RuntimeError exception. The method returns a RuntimeError exception if the allowSaveRouteData property on the solver object is set to False. |
searchCursor (output_type, field_names, {where_clause}) | Establishes a search cursor on the specified output type. This cursor can be used to read rows directly from the output. |
solverMessages (severity) | Get error, warning, and informational messages returned by the solver. |
Methoden
count (output_type)
Parameter | Erklärung | Datentyp |
output_type | The type of output features to count. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration. | Object |
Datentyp | Erklärung |
Integer | The number of rows. |
Raises no exception.
export (output_type, output_features)
Parameter | Erklärung | Datentyp |
output_type | The type of output to export. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration. | Object |
output_features | The catalog path to the output feature class or table that will contain the exported features. | String |
fieldNames (output_type)
Parameter | Erklärung | Datentyp |
output_type | The type of output for which to return a list of field names. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration. | Object |
Datentyp | Erklärung |
String | A list of field names supported by the specified output type. |
saveAsLayerFile (file_name)
Parameter | Erklärung | Datentyp |
file_name | The catalog path of the output layer file (.lyr) to write. | String |
saveRouteData (file_name)
Parameter | Erklärung | Datentyp |
file_name | The full path of the output .zip file. | String |
searchCursor (output_type, field_names, {where_clause})
Parameter | Erklärung | Datentyp |
output_type | The type of output to read. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration. | Object |
field_names [field_names,...] | A list of field names of the output type whose values the cursor will return. You can get the names of the fields that are supported by an output type using the fieldNames method. In addition to regular fields, you can also access the geometry of the output using one of the following geometry tokens:
The SHAPE@XY and SHAPE@XYZ tokens are only supported for point-based output types. | String |
where_clause | Ein optionaler Ausdruck zur Begrenzung der zurückgegebenen Datensätze. Weitere Informationen zu WHERE-Klauseln und SQL-Anweisungen finden Sie unter SQL-Referenz für in Abfrageausdrücken verwendete Elemente. (Der Standardwert ist None) | String |
Datentyp | Erklärung |
Object | A SolverResultSearchCursor object that reads rows from the output. |
solverMessages (severity)
Parameter | Erklärung | Datentyp |
severity | The type of messages to be returned. The parameter should be specified using the MessageSeverity enumeration. | Object |
Datentyp | Erklärung |
List | The messages are returned as a list of lists. The inner list contains two values; the first is a number representing the message code, and the second value is the message text. An example of a list of messages returned from a failed origin destination cost matrix analysis. |
