VehicleRoutingProblemResult

Resumen

An object containing the results of a vehicle routing problem analysis that can be used to access outputs and solver messages.

Debate

Instances of this class cannot be created directly. Instead, they are returned by the solve method of the VehicleRoutingProblem class.

Propiedades

Propiedad	Explicación	Tipo de datos
isPartialSolution (Sólo lectura)	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 (Sólo lectura)	Returns True if the solve was successful.	Boolean
spatialReference (Sólo lectura)	Returns the spatial reference of the output features. For example, feature classes created using the export method and geometry objects retrieved from the searchCursor method will have this spatial reference. The spatialReference value is typically the spatial reference of the network dataset or service used in the analysis.	SpatialReference

Descripción general del método

Método	Explicación
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. When using the VehicleRoutingProblemSchemaVersion.One schema version, 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.
extent ({output_type})	Returns the extent of the analysis output. The method returns a RuntimeError exception if the analysis solve failed.
fieldNames (output_type)	Returns a list of field names supported by a specified output type.
saveAsLayerFile (file_name)	Save the analysis result and settings to a layer file or layer package. The layer file or package can be opened in ArcGIS Pro as a record of the analysis settings or to visualize the results. A layer file can also be opened in ArcGIS Desktop. The method returns a RuntimeError exception if the allowSaveLayerFile property on the solver object is set to False. Heredado: Routing services based on portals running versions of ArcGIS Enterprise older than 10.9 do not support saving layer packages. The method returns a RuntimeError exception if this is the case.
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. Los elementos de capa de ruta pueden usarse desde distintas aplicaciones, por ejemplo, ArcGIS Navigator para proporcionar indicaciones de ruta a los trabajadores móviles, el panel Indicaciones de Map Viewer Classic para personalizar aún más la ruta contenida en la capa de ruta, y ArcGIS Pro para crear una capa de análisis de ruta a partir de una capa de ruta. 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.

Métodos

count (output_type)

Parámetro	Explicación	Tipo de datos
output_type	The type of output features to count. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemOutputDataType2 enumeration when using the VehicleRoutingProblemSchemaVersion.Two schema version.	Object

Valor de retorno

Tipo de datos	Explicación
Integer	The number of rows.

Raises no exception.

export (output_type, output_features)

Parámetro	Explicación	Tipo de datos
output_type	The type of output to export. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemOutputDataType2 enumeration when using the VehicleRoutingProblemSchemaVersion.Two schema version. See descriptions of the fields included in each output type when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemSchemaVersion.Two schema version.	Object
output_features	The catalog path to the output feature class or table that will contain the exported features.	String

extent ({output_type})

Parámetro	Explicación	Tipo de datos
output_type	The type of output features for which to get the extent. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemOutputDataType2 enumeration when using the VehicleRoutingProblemSchemaVersion.Two schema version. If you do not specify a value, or you specify a value of None, the extent for the combined analysis outputs is returned.	Object

Valor de retorno

Tipo de datos	Explicación
Extent	An arcpy.Extent object indicating the extent of the designated output type.

fieldNames (output_type)

Parámetro	Explicación	Tipo de datos
output_type	The type of output for which to return a list of field names. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemOutputDataType2 enumeration when using the VehicleRoutingProblemSchemaVersion.Two schema version. See descriptions of the fields included in each output type when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemSchemaVersion.Two schema version.	Object

Valor de retorno

Tipo de datos	Explicación
String	A list of field names supported by the specified output type.

saveAsLayerFile (file_name)

Parámetro	Explicación	Tipo de datos
file_name	The catalog path of the output layer file (.lyr) or layer package (.lpkx) to write. Precaución: Layer files with an .lyr extension cannot be saved if the solver object uses a service URL as its network data source. The method returns a RuntimeError exception in this case.	String

saveRouteData (file_name)

Parámetro	Explicación	Tipo de datos
file_name	The full path of the output .zip file.	String

searchCursor (output_type, field_names, {where_clause})

Parámetro	Explicación	Tipo de datos
output_type	The type of output to read. The parameter should be set using the VehicleRoutingProblemOutputDataType enumeration when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemOutputDataType2 enumeration when using the VehicleRoutingProblemSchemaVersion.Two schema version.	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. See descriptions of the fields included in each output type when using the VehicleRoutingProblemSchemaVersion.One schema version or the VehicleRoutingProblemSchemaVersion.Two schema version. In addition to regular fields, you can also access the geometry of the output using one of the following geometry tokens: SHAPE@XY—A tuple of the feature's centroid's x- and y-coordinates. SHAPE@XYZ—A tuple of the feature's centroid's x-, y-, and z-coordinates. SHAPE@JSON— The Esri JSON string representing the geometry. SHAPE@WKB—The well-known binary (WKB) representation for OGC geometry. It provides a portable representation of a geometry value as a contiguous stream of bytes. SHAPE@WKT—The well-known text (WKT) representation for OGC geometry. It provides a portable representation of a geometry value as a text string. SHAPE@—A geometry object for the feature. The SHAPE@XY and SHAPE@XYZ tokens are only supported for point-based output types. The x-, y-, and z-values returned when using the SHAPE@XY and SHAPE@XYZ tokens are in the spatial reference reported by the solver result object's spatialReference property, and this is typically the same as the spatial reference of the network data source used for the analysis.	String
where_clause	Una expresión opcional que limita los registros que se devuelven. Para obtener más información sobre cláusulas WHERE y sentencias SQL, consulte Referencia de SQL para las expresiones de consulta utilizadas en ArcGIS. (El valor predeterminado es None)	String

Valor de retorno

Tipo de datos	Explicación
Object	A SolverResultSearchCursor object that reads rows from the output.

solverMessages (severity)

Parámetro	Explicación	Tipo de datos
severity	The type of messages to be returned. The parameter should be specified using the MessageSeverity enumeration.	Object

Valor de retorno
