A different approach is taken for supporting casting smart pointers up the
inheritance hierarchy. We no longer try to replace the underlying pointer type,
provided in the 'feature:smartptr', with the base class type. Such as morphing
'std::shared_ptr<(Derived)>' into 'std::shared_ptr<(Base)>'. Instead, we simply
use 'feature:smartptr' from the base class. This is more reliable than trying to
pattern match the pointer type in the feature. The base class must of course
also have the 'feature:smartptr' set, and this is still checked for as before.
The feature is now parsed in one place and stored in the parse tree in the
new 'smart' attribute for handling by the target languages.
Fix also improves the handling of the type parsed in 'feature:smartptr' in that
the type is now normalized and resolved in the scope of the class it is attached
to.
Closes#2768
The sym:overname attribute was not being updated when templates were
included in the list of overloaded methods/constructors, leading to
duplicate target language symbols in some language like java/csharp.
Closes#2541
Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Required reworking code that adds a fake inheritance for smart pointers
using the smartptr feature. Swig_smartptr_upcast() added as a support
function for this.
%inline %{
class Foo {
protected:
void x();
public:
void y();
};
%}
will work in plain or plain director mode, but it will complain the
same as before with director protected support.
The reason is that the parser emmits the warning, and at that stage it
is not possible to decide if the protected Foo::x() could or not
conflict with the renamed Foo::y(), since Foo::x() could be virtual,
even when no "virtual" attribute is used.
Core:
parser.y: Detect the dirprot mode and prevents the generation of
protected symbols at the parsing stage.
lang.cxx: Export the director_protected_mode for parser.y and the
director protected member detection is much cleaner.
main.cxx: Fix the -dirprot flag, it was working in SWIG_FEATURE but
not in the command line.(minor thing not relate to the error).
swigmod.h: added Lang::dirprot_mode() for cleaner detection.
utils.cxx: is_member_director() centralizes and improve the test.
Test suite:
protected_rename.i: added %inline, so it can compile now.
director_protected.i: more cases, checking using %rename.
