Detailed Description

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.

Constructor & Destructor Documentation

UnifiedAutomation.UaBase.QueryNextRequest.QueryNextRequest ( )

inline

The default constructor.

Member Function Documentation

virtual bool UnifiedAutomation.UaBase.QueryNextRequest.IsEqual ( IEncodeable  encodeable )

inlinevirtual

Checks if encodeable is the same object or has the same content

Parameters

encodeable

Returns

Implements UnifiedAutomation.UaBase.IEncodeable.

Property Documentation

byte [] UnifiedAutomation.UaBase.QueryNextRequest.ContinuationPoint

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.

bool UnifiedAutomation.UaBase.QueryNextRequest.ReleaseContinuationPoint

getset

A boolean parameter indicating whether continuation points should be released.

It has the following values:

TRUE

passed ContinuationPoints shall be reset to free resources in the Server.

FALSE

passed ContinuationPoints shall be used to get the next set of QueryDataSEts.

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.
