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.
- Add missing vector copy constructor
- Add constructor to initialize the containers. Note that Java's
equivalent constructor for ArrayList just sets the capacity, whereas
the wrappers behave like the C++ constructor and set the size. I've
done this mainly because there has been a vector(size_type) constructor
in the Java wrappers for many years, so best to keep this unchanged.
It doesn't seem to be possible to have a Java collection with more than 2^31-1
items, but it is perfectly possible to have an std::vector with more elements
than that in C++, so add runtime checks verifying that we don't lose count of
elements in the Java wrappers.
Derive the class wrapping std::vector<> in Java from java.util.AbstractList<>.
This makes it possible to use it with various algorithms working with Java
collections and, maybe even more importantly, makes it possible to iterate
over the wrapped vectors using for-each loops.
This commit is based on the original patch by Volker Diels-Grabsch from
https://sourceforge.net/p/swig/patches/278/
No real changes yet, just use a C#-like macro in Java std::vector<> typemaps
too to avoid having to repeat almost exactly the same class declaration for
the general case and for the bool specialization.
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.
