Résumé
An object containing the results of a closest facility analysis that can be used to access outputs and solver messages.
Discussion
Instances of this class cannot be created directly. Instead, they are returned by the solve method of the ClosestFacility class.
Propriétés
Propriété | Explication | Type de données |
isPartialSolution (Lecture seule) | 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 (Lecture seule) | Returns True if the solve was successful. | Boolean |
Vue d’ensemble des méthodes
Méthode | Explication |
count (output_type) | Returns the number of rows for an output type. |
export (output_type, output_features) | The output features will be created in the spatial reference of the network dataset used for the analysis. If the arcpy.env.outputCoordinateSystem environment is set, the output features will be created with the specified coordinate system instead. Exports the analysis results to a feature class or table. |
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. The layer file can be opened in ArcGIS Desktop or ArcGIS Pro as a record of the analysis settings or to visualize the results. 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. Un élément de couche d’itinéraire peut être utilisé par diverses applications. Dans ArcGIS Navigator, par exemple, il permet de guider les équipes dépêchées sur le terrain, via la fenêtre Directions (Feuille de route) du module Map Viewer afin de personnaliser davantage l’itinéraire figurant dans la couche d’itinéraire ou via ArcGIS Pro pour créer une couche d’analyse d’itinéraires à partir d’une couche d’itinéraire. 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. |
Méthodes
count (output_type)
Paramètre | Explication | Type de données |
output_type | The type of output features to count. The parameter should be set using the ClosestFacilityOutputDataType enumeration. | Object |
Type de données | Explication |
Integer | The number of rows. |
Raises no exception.
export (output_type, output_features)
Paramètre | Explication | Type de données |
output_type | The type of output to export. The parameter should be set using the ClosestFacilityOutputDataType enumeration. | Object |
output_features | The catalog path to the output feature class or table that will contain the exported features. | String |
fieldNames (output_type)
Paramètre | Explication | Type de données |
output_type | The type of output for which to return a list of field names. The parameter should be set using the ClosestFacilityOutputDataType enumeration. | Object |
Type de données | Explication |
String | A list of field names supported by the specified output type. |
saveAsLayerFile (file_name)
Paramètre | Explication | Type de données |
file_name | The catalog path of the output layer file (.lyr) to write. | String |
saveRouteData (file_name)
Paramètre | Explication | Type de données |
file_name | The full path of the output .zip file. | String |
searchCursor (output_type, field_names, {where_clause})
Paramètre | Explication | Type de données |
output_type | The type of output to read. The parameter should be set using the ClosestFacilityOutputDataType 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 | Expression optionnelle qui limite les enregistrements retournés. Pour en savoir plus sur les clauses WHERE et les instructions SQL, consultez Référence SQL pour les éléments utilisés dans les expressions de la requête. (La valeur par défaut est None) | String |
Type de données | Explication |
Object | A SolverResultSearchCursor object that reads rows from the output. |
solverMessages (severity)
Paramètre | Explication | Type de données |
severity | The type of messages to be returned. The parameter should be specified using the MessageSeverity enumeration. | Object |
Type de données | Explication |
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. |
