Introduction

connectedEdges represents connectivity analysis. By sending a Get request to connectedEdges, the system can find the connected nodes and edges according to the specified node or edge.

Supported Methods:

Supported output formats: RJSON, JSON, HTML, XML.

Resource hierarchy

HTTP request methods

Execute HTTP request on the following URI, here we take rjosn as the output format as an example. Where, supermapiserver is the server name.

http://supermapiserver:8090/iserver/services/transportationAnalyst-facilityNet/rest/networkanalyst/WaterNet@FacilityNet/connectededges.rjson

GET request

Finds the connected nodes and edges according to the specified node or edge.

Request parameter

To execute a GET request on connectedEdges resource, the URI should contain the following parameters:

Name Type Description
connected boolean Whether to find connected edges or unconnected edges. true indicates finding connected edges, while false will find unconnected edges.
returnFeatures boolean Whether to return a detailed description of the result feature. false indicates only returning the IDs of the features.
edgeIDs int[] The IDs of the connected edges of the analysis result.
nodIDs int[] The IDs of the connected nodes of the analysis result.

Response structure

After executing connectivity analysis, the response fields of the result representation are as follows:

Name Type Description
cost double The cost of the connectivity analysis.
edges int[] The IDs of the result edges.
edgesFeatures Feature[] The detailed information of the result edges.
nodes int[] The IDs of the result nodes.
nodesFeature Feature[] The detailed information of the result nodes.

Response example

Execute connectivity analysis to sample dataset "WaterNet@FacilityNet", ie., sending a GET request by using the following URI:

http://supermapiserver:8090/iserver/services/transportationAnalyst-facilityNet/rest/networkanalyst/WaterNet@FacilityNet/connectededges.rjson?connected=true&returnFeatures=true&edgeIDs=[401,420,57]

A part of the analysis result is as follows:

HEAD request

Returns the same HTTP response header as the GET request, but no response entity, which can be used to retrieve the meta data contained in response message header without having to transmit the entire response content. Meta data information includes media type, character coding, compression coding, entity content length, etc.

HEAD request is used to determine whether the connectedEdges resource exists, or if the user has the authority to access it. By executing an HEAD request with a .<format> URI, you can quickly determine whether the connectedEdges resource supports the <format> representation.
