VehicleRoutingProblemResult

概要

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

ディスカッション

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

プロパティ

プロパティ	説明	データ タイプ
isPartialSolution (読み取り専用)	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 (読み取り専用)	Returns True if the solve was successful.	Boolean

手法の概要

手法	説明
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.
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. A layer package cannot be saved if the analysis references a portal service as the network data source. The method returns a RuntimeError exception if the allowSaveLayerFile property on the solver object is set to False.
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. ルート レイヤー アイテムは、現場作業者にルート ガイダンスを提供する場合には、ArcGIS Navigator などの各種アプリケーションで使用し、ルート レイヤーに含まれているルートをカスタマイズする場合には、Map Viewer の [ルート案内] ウィンドウで使用し、ルート レイヤーから新しいルート解析レイヤーを作成する場合には、ArcGIS Pro で使用することができます。 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.

手法

count (output_type)

パラメーター	説明	データ タイプ
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

戻り値

データ タイプ	説明
Integer	The number of rows.

Raises no exception.

export (output_type, output_features)

パラメーター	説明	データ タイプ
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

fieldNames (output_type)

パラメーター	説明	データ タイプ
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

戻り値

データ タイプ	説明
String	A list of field names supported by the specified output type.

saveAsLayerFile (file_name)

パラメーター	説明	データ タイプ
file_name	The catalog path of the output layer file (.lyr) or layer package (.lpkx) to write.	String

saveRouteData (file_name)

パラメーター	説明	データ タイプ
file_name	The full path of the output .zip file.	String

searchCursor (output_type, field_names, {where_clause})

パラメーター	説明	データ タイプ
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 x,y coordinates. SHAPE@XYZ —A tuple of the feature's centroid x,y,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 of the network data source used for the analysis.	String
where_clause	An optional expression that limits the records returned. For more information on WHERE clauses and SQL statements, see SQL reference for query expressions used in ArcGIS. (デフォルト値は次のとおりです None)	String

戻り値

データ タイプ	説明
Object	A SolverResultSearchCursor object that reads rows from the output.

solverMessages (severity)

パラメーター	説明	データ タイプ
severity	The type of messages to be returned. The parameter should be specified using the MessageSeverity enumeration.	Object

説明

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".']]
