Detailed Description

The xstring_context_t class is used to add context sensitivity to xstring lookups. Example:

{
    adobe::attribute_set_t attribute_set;

    attribute_set.push_back(std::make_pair(adobe::static_name_t("context"), adobe::static_name_t("some_view")));

    adobe::xstring_context_t mycontext(attribute_set);

    // anything here is looked up with the context='some_view'; other attributes remain unchanged
}
// now our context is out scope and we go back to what we had before.

There is also a constructor that takes a name/value pair for simple context construction. Example:

{
    adobe::xstring_context_t mycontext(adobe::static_name_t("context"), adobe::static_name_t("some_view"));

    // anything here is looked up with the context='some_view'; other attributes remain unchanged
}
// now our context is out scope and we go back to what we had before.

There is also a constructor that takes a set of std::pair<adobe::name_t, adobe::name_t> for simple context construction. Example:

{
    std::vector<std::pair<adobe::name_t, adobe::name_t> > my_set;

    // fill in my_set ...

    adobe::xstring_context_t mycontext(&my_set[0], &my_set[my_set.size()]);

    // anything here is looked up with a context affected by my_set
}
// now our context is out scope and we go back to what we had before.
