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

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. 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. Los elementos de capa de ruta pueden usarse desde distintas aplicaciones, por ejemplo, ArcGIS Navigator para proporcionar indicaciones de ruta a los trabajadores de campo, el panel Indicaciones de Map Viewer para personalizar aún más la ruta contenida en la capa de ruta, o bien ArcGIS Pro para crear una nueva 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.	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.	Object
output_features	The catalog path to the output feature class or table that will contain the exported features.	String

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.	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) to write.	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.	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: SHAPE@XY —Una tupla de las coordenadas x,y del centroide de la entidad. SHAPE@XYZ —Una tupla de las coordenadas x, y, z del centroide de la entidad. Este token solo se admite cuando la geometría está habilitada para z. SHAPE@JSON — La cadena de caracteres JSON de Esri que representa la geometría. SHAPE@WKB —Representación binaria conocida (WKB) para geometría OGC. Ofrece una representación portátil de un valor de geometría como una transmisión contigua de bytes. SHAPE@WKT —Representación en texto conocida (WKB) para geometría OGC. Ofrece una representación portátil de un valor de geometría como cadena de caracteres. SHAPE@ —Objeto de geometría para la entidad. The SHAPE@XY and SHAPE@XYZ tokens are only supported for point-based output types.	String
where_clause	Una expresión opcional que limita los registros que se devuelven. Para obtener más información sobre las cláusulas WHERE y sentencias SQL, consulte Referencia SQL para los elementos utilizados en las expresiones de consulta. (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

Tipo de datos

Explicación

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. [[-2147200995, '0 location(s) in "Destinations" are valid. Need at least 1 valid location(s).'], [30024, 'Solve returned a failure.'], [-2147200995, 'Insufficient number of valid locations in "Origins" or "Destinations".']]
