Hi,

I know how template is used in C++. However, in the following codes, I am not quite understand the line of "public ParcelType::template TrackingData<CloudType>". What is the keyword template is used for here?

     template<class CloudType>
     class TrackingData
     :
         public ParcelType::template TrackingData<CloudType>
     {
     public:
 
         enum trackPart

//Kai

CloudType

The rest is to assure that the message I have entered is not too short, so that I can be allowed to push `Submit Reply` button.

Hi HPE,

Thank your for your answers. Could you please help me to understand the structure of codes

public ParcelType::template TrackingData<CloudType>

I cannot find any examples or references elsewhere as template is used here.
