[xsde-users] Migration from XSD to XSD/e

[kelvin manoj]

Hi,

I am trying to migrate from XSD to XSD/e for the below project available in
github. This I am doing for reducing the memory usage. XSD consuming lot of
memory with xerces.

So I believe if I migrate the project to XSD/e I can save some memory.

Is it possible to migrate the XSD to XSD/e if some application already
using XSD. I don't wanted to modify the application code.

Project I am trying to migrate:
https://github.com/epri-dev/OpenADR-VEN-Library

I have compiled the schema files using XSD/e but after including in the
project I am seeing lot of things are missing. Some places where I am
getting errors commonly are given below.

XSD:
typedef ::icalendar_2_0::DateTimeType date_time_type;

XSD/e:
Here there is no such inner typedef. So I am getting bellow error while
building my application
error C2039: 'date_time_type' : is not a member of 'icalendar_2_0::dtstart'

If I try to resolve the above error by replacing the date_time_type with
::icalendar_2_0::DateTimeType I am getting below issue related to that.

XSD:
      template <typename C, typename B>
      inline date_time<C, B>::
      date_time (int year, unsigned short month, unsigned short day,
                 unsigned short hours, unsigned short minutes, double
seconds,
                 short zone_h, short zone_m)
          : time_zone (zone_h, zone_m),
            year_ (year), month_ (month), day_ (day),
            hours_ (hours), minutes_ (minutes), seconds_ (seconds)
      {
      }

XSD/e:
    inline date_time::
    date_time (int year, unsigned short month, unsigned short day,
               unsigned short hours, unsigned short minutes, double seconds,
               short zone_h, short zone_m)
        : time_zone (zone_h, zone_m),
          year_ (year), month_ (month), day_ (day),
          hours_ (hours), minutes_ (minutes), seconds_ (seconds)
    {
    }
Here template is missing so it throws below error
error C2664: 'icalendar_2_0::DateTimeType::DateTimeType(const
icalendar_2_0::DateTimeType &)' : cannot convert argument 1 from
'xsde::cxx::date_time' to 'const icalendar_2_0::DateTimeType &'
I am not sure If i am missing any options in the compile command. Here is
the command I used to compile:
xsde cxx-hybrid --root-element oadrPayload --file-per-type
--generate-parser --generate-serializer --generate-polymorphic
--polymorphic-type ItemBaseType --polymorphic-type EnergyItemType
--polymorphic-type PowerItemType --polymorphic-type PayloadBaseType
--polymorphic-type StreamPayloadBaseType --polymorphic-type UidType
