[xsde-users] Q: Overriding an optional field (BaseURL)

[Rangarajan, Ravi_Sowmian]

Hi Boris,
Thanks so much for your response. I have included the errors I get for option 1, which you think should work. I have also tried few other options and errors for those included below. It will be great to hear from you on what is missing and get it resolved.
Thanks
Ravi

1)
*baseUrlIter = customBaseUrl

Mymodule.cpp:1417: error: no match for operator= in baseUrlIter.xsd::cxx::tree::iterator_adapter<I, T>::operator* [with I = __gnu_cxx::__normal_iterator<xsd::cxx::tree::sequence_common::ptr*, std::vector<xsd::cxx::tree::sequence_common::ptr, std::allocator<xsd::cxx::tree::sequence_common::ptr> > >, T = mpd_2011::BaseURLType]() = customBaseUrl

../../../../../lib/eps/epc/bmsc/xsd/MPD2.h:3646: note: candidates are: mpd_2011::BaseURLType& mpd_2011::BaseURLType::operator=(const mpd_2011::BaseURLType&)
In file included from ../../../../../thirdParty/codesynthesis/libxsd/xsd/cxx/tree/list.hxx:16,
                 from ../../../../../thirdParty/codesynthesis/libxsd/xsd/cxx/tree/types.hxx:26,
                 from ../../../../../lib/eps/epc/bmsc/xsd/xml.h:62,
                 from Mymodule.h:39,
                 from Mymodule.cpp:43

The other alternatives I have thought about (not successful yet in getting either to work) are:

a)
(*baseUrlIter).serviceLocation.set(customBaseUrl);
(*baseUrlIter).byteRange.set("")

c)
construct an object of type BaseUrlType say newBaseUrl and then assign to
(*baseUrlIter) = newBaseUrl;

But am getting errors below for option a and I haven't been successful constructing a BaseURLType object that can be assigned to (*baseUrlIter).

Mymodule.cpp:1150: error: burlIter.xsd::cxx::tree::iterator_adapter<I, T>::operator* [with I = __gnu_cxx::__normal_iterator<xsd::cxx::tree::sequence_common::ptr*, std::vector<xsd::cxx::tree::sequence_common::ptr, std::allocator<xsd::cxx::tree::sequence_common::ptr> > >, T = mpd_2011::BaseURLType]()->mpd_2011::BaseURLType::serviceLocation does not have class type

Hi Ravi,

This should work. Specifically:

MPD_2011::MPDtype::BaseURL_sequence &BaseURLseq = myMPD->BaseURL(); MPD_2011::MPDtype::BaseURL_iterator baseUrlIter = BaseURLseq.begin(); if (baseUrlIter != BaseURLseq.end()) {
  *baseUrlIter = customBaseUrl;
}

If this still doesn't work, can you be more specific than "it doesn't like it" (i.e., compiler error, runtime behaviour is wrong, etc)?
