Methods

burstPipelineAnalyst(params, callback)

NetworkAnalystService.js, line 45

Analysis the burst pipeline: analyze the given edge or node as the pipeline burst node, and return the critical node ID array, common node ID array and upstream/downstream edge ID array.

Name	Type	Description
params	SuperMap.BurstPipelineAnalystParameters	The BurstPipelineAnalystParameters class.
callback	RequestCallback	The callback of result data returned by the server side.

computeWeightMatrix(params, callback)

NetworkAnalystService.js, line 66

Compute weight of matrix. The costs matrix refers to a 2D matrix computed by the costs fields in the traffic network analysis parameters, which is used to store the resources costs between each pairs of the specified points.

Name	Type	Description
params	SuperMap.ComputeWeightMatrixParameters	The ComputeWeightMatrixParameters class.
callback	RequestCallback	The callback of result data returned by the server side.

inherited destroy()

ServiceBase.js, line 44

Disposes the resource. The property that references resource is set to null.

findClosestFacilities(params, callback, resultFormat)

NetworkAnalystService.js, line 87

Find closest facilities. It is used to find the closest facilities from the selected ones for the specified event site(s) in the network. The closest facilities are those that have the least impedance in the specified direction -- either from the event site to the facility or from the facility to the event site.

Name	Type	Default	Description
params	SuperMap.FindClosestFacilitiesParameters		The FindClosestFacilitiesParameters class.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

findLocation(params, callback, resultFormat)

NetworkAnalystService.js, line 133

Find location. It is used to find the optimal location from multiple candidate locations for a facility, by matching the supply and demand based on the objectives and constraints.

Name	Type	Default	Description
params	SuperMap.FindLocationParameters		The parameters of findLocation.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

findPath(params, callback, resultFormat)

NetworkAnalystService.js, line 156

Find optimal path. The optimal path analysis refers to finding the path with the minimum cumulative impedance by visiting all the specified nodes in order.

Name	Type	Default	Description
params	SuperMap.FindPathParameters		The FindPathParameters class.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

findServiceAreas(params, callback, resultFormat)

NetworkAnalystService.js, line 225

Find service areas. It is a kind of network analysis, used to determine the area that can be served by a service site based on specified criteria.

Name	Type	Default	Description
params	SuperMap.FindServiceAreasParameters		The FindServiceAreasParameters class.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

findTSPPaths(params, callback, resultFormat)

NetworkAnalystService.js, line 179

Find paths of traveler. TSP is an unordered route analysis. It starts from the Start point (the default is the first point that you specify), and finds a route that traverses all nodes with minimum cost. You may also specify an End point. Thus, It finds a route that traverses all nodes and arrives at the End point with minimum cost.

Name	Type	Default	Description
params	SuperMap.FindTSPPathsParameters		The FindTSPPathsParameters class.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

streamFacilityAnalyst(params, callback, resultFormat)

NetworkAnalystService.js, line 110

Find key facilities in the upstream and downstream. It returns the key node ID array and its downstream arc segment ID array by finding key facility nodes in the upstream/downstream of a given arc or node.

Name	Type	Default	Description
params	SuperMap.FacilityAnalystStreamParameters		The FacilityAnalystStreamParameters class.
callback	RequestCallback		The callback of result data returned by the server side.
resultFormat	SuperMap.DataFormat	SuperMap.DataFormat.GEOJSON	optional The format of result data.

updateEdgeWeight(params, callback)

NetworkAnalystService.js, line 248

Update the weight of edge.

Name	Type	Description
params	SuperMap.UpdateEdgeWeightParameters	The UpdateEdgeWeightParameters class.
callback	RequestCallback	The callback of result data returned by the server side.

updateTurnNodeWeight(params, callback)

NetworkAnalystService.js, line 269

Update the weight of turn node.

Name	Type	Description
params	SuperMap.UpdateTurnNodeWeightParameters	The UpdateTurnNodeWeightParameters class.
callback	RequestCallback	The callback of result data returned by the server side.
