Class QueryResult

java.lang.Object

com.microsoft.azure.sdk.iot.provisioning.service.configs.QueryResult

public class QueryResult
extends Object

Representation of a single Device Provisioning Service query response with a JSON deserializer.

It is the result of any query for the provisioning service. This class will parse the result and return it in a best format possible. For the known formats in QueryResultType, you can just cast the items. In case of unknown type, the items will contain a list of Strings and you shall parse it by your own.

The system properties are:

type:

Identify the type of the content in the body. You can use it to cast the objects in the items list. See QueryResultType for the possible types and classes to cast.

continuationToken:

Contains the token the uniquely identify the next page of information. The service will return the next page of this query when you send a new query with this token,

And the body is a JSON list of the specific type. For instance, if the system property type is IndividualEnrollment, the body will look like:

 
 [
     {
         "registrationId":"validRegistrationId-1",
         "deviceId":"ContosoDevice-1",
         "attestation":{
             "type":"tpm",
             "tpm":{
                 "endorsementKey":"validEndorsementKey"
             }
         },
         "iotHubHostName":"ContosoIoTHub.azure-devices.net",
         "provisioningStatus":"enabled"
     },
     {
         "registrationId":"validRegistrationId-2",
         "deviceId":"ContosoDevice-2",
         "attestation":{
             "type":"tpm",
            "tpm":{
                 "endorsementKey":"validEndorsementKey"
             }
         },
         "iotHubHostName":"ContosoIoTHub.azure-devices.net",
         "provisioningStatus":"enabled"
     }
 ]
