This Service is used to request the next set of QueryFirst or QueryNext response information that is too large to be sent in a single response.
“Too large” in this context means that the Server is not able to return a larger response or that the number of QueryDataSets to return exceeds the maximum number of QueryDataSets to return that was specified by the Client in the original request. The QueryNext shall be submitted on the same session that was used to submit the QueryFirst or QueryNext that is being continued.

Implements UnifiedAutomation.UaBase.IEncodeable.
|
getset |
Server defined opaque value that represents the continuation point.
The value of the continuation point was returned to the Client in a previous QueryFirst or QueryNext response. This value is used to identify the previously processed QueryFirst or QueryNext request that is being continued, and the point in the result set from which the browse response is to continue.
|
getset |
A boolean parameter indicating whether continuation points should be released.
It has the following values:
A Client shall always use the continuation point returned by a QueryFirst or QueryNext response to free the resources for the continuation point in the Server. If the Client does not want to get the next set of Query information, QueryNext shall be called with this parameter set to TRUE.
If the parameter is set to TRUE, all array parameters in the response shall contain empty arrays.
