Workaround clang++ 9.1.0 error not knowing std::vector<bool>::const_reference
is actually typedef to bool:
li_std_vector_wrap.cxx:1838:40: error: no matching constructor for initialization of 'std::vector<bool>::const_reference'
Workaround is use
const value_type& getitem(int index) throw (std::out_of_range) { ...
// bool specialization:
bool getitem(int index) throw (std::out_of_range) { ...
instead of
const_reference_type getitem(int index) throw (std::out_of_range) { ...
Although the following would be better, it would require a more
complicated implementation:
const_reference_type getitem(int index) throw (std::out_of_range) { ...
// bool specialization:
bool getitem(int index) throw (std::out_of_range) { ...
For users who have typemaps for the parameters in the setitem method.
Correct definitions of const_reference to match the those in the
(C++11) standard.
Assignable fixes are based on those used by C# std::vector where the
default wrappers work if there is no operator== available in the
template type. Enhanced wrappers are obtained via a macro:
SWIG_STD_LIST_ENHANCED(SomeNamespace::Klass)
%template(ListKlass) std::list<SomeNamespace::Klass>;
Remove bool specialization (left over from the original std::vector
wrappers).
Add in missing typedefs.
Tests for std::vector of pointers added which check
std::vector<T*>::const_reference and std::vector<T*>::reference
usage which gave compilation errors in Python and Perl which had
specialized these vectors incorrectly.
The C# type corresponding to size_t may be changed by redefining its "cstype"
type typemap, but this broke compilation of the code using std::vector<> as
the typemap generating it assumed that size_t was always represented by uint
in C#. Make this work in all cases by explicitly looking up cstype of size_t
instead.
Notice that it may be quite useful, and even necessary, to map size_t to int
as when generating C# assembly for use with COM, via .NET interop, as some COM
clients, notably VBA-using ones, including all Microsoft Office applications,
don't support unsigned types and can't call methods using or returning uint in
C# at all.
Adding a constructor that accepts IEnumerable<T> avoids the boxing and unboxing overhead of the original constructor, when the type parameter is a value type. This also allows passing IList<T>, which does not implement ICollection (ironically the generated type implements IList<T>).
Kept the original constructor for backward compatibility, but replaced ICollection with IEnumerable for added flexibility.
1) The %extend directive can now optionally support one of the 'class', 'struct' or 'union'.
2) The SWIG library no longer uses the javatype, dtype or cstype typemaps, thereby
completely freeing them up for users to use without having to replicate the library
code that they previously added
Tested by changes to test: java_lib_arrays
clang++ using -stdlib=libc++ defines const_reference as a class,
to map boolean vectors onto a bit set. Because swig does
not "see" the type as "const &" it generates incorrect code for this case,
generating a declaration like:
const_reference result;
When const_reference is a typedef to 'bool' as is the case with stdlibc++
this works. When this is actually a constant reference, this is clearly
invalid since it is not initialized. For libc++, this is a class
which cannot be default constructed, resulting in an error. The fix
is to explicitly define the various accessor extensions as having a
bool return type for this specialization.
