[xsd-users] Howto avoid slicing with xsd-types to std::string

[Tempelaar E. (Erik)]

Thank you for getting back to me so soon.

Here's the exact message for the code below:

" Use pointer or reference to avoid slicing from "string<char, xsd::cxx::tree::simple_type<char, xsd::cxx::tree::_type>>" to "basic_string<char>"

    if (cfg->Configuration().ProjectFolder().present()) {

      m_projectFolder = cfg->Configuration().ProjectFolder().get();


with: m_projectFolder:
std::string m_projectFolder{""};

<xsd:element name="ProjectFolder" type="xsd:string" minOccurs="0">
</xsd:element>


But there's others like this one (not only the optionals), i.e.:
"Use pointer or reference to avoid slicing from "Title_t" to "basic_string<char>"

Best regards,
Erik

Can you show an example of the code that produces such a warning and the warning diagnostics that you are getting for it?
