REASON: We use GSON.fromJson() to parse the JSON data received from DB into a DataNode Object. It is unable to parse Integers and defaults all numerical data to Double Objects.

 

Attached are YANG file and associated JSON payload used for testing.

Node is created in CPS-Core using, POST http://localhost:8883/cps/api/v1/dataspaces/E2EDemo/anchors/coverage-area-onap/nodes

When following query is performed, 

http://localhost:8883/cps/api/v1/dataspaces/E2EDemo/anchors/coverage-area-onap/nodes/query?cps-path=/ran-coverage-area&include-descendants=true

 

following result is obtained, and not sure why "decimal point and 0" are included in the value (most probably as String?)

The below XPATH query works

 sandeepos@sandeepos-Gazelle:~/NetworkSlicing/configDB/CPS/gerrit/Aug2021/common-cps-and-tbdmt/common$ curl -g -H "Authorization: Basic Y3BzdXNlcjpjcHNyMGNrcyE=" --request GET 'http://localhost:8883/cps/api/v1/dataspaces/E2EDemo/anchors/coverage-area-onap/node?xpath=/ran-coverage-area/pLMNIdList[@mcc=%27310%27%20and%20@mnc=%27410%27]/coverage-area[@coverageArea=%27Chennai%27]/coverageAreaTAList[@nRTAC=%27101%27]&include-descendants=true'

{"nRTAC":101.0,"taCellsList":[

{"cellLocalId":15296.0}

,{"cellLocalId":15289.0},{"cellLocalId":15290.0}]} 

However - please advise why above values have decimal point and 0 included? 

Thanks!
