I have some further unrelated design questions/points:
From what I understand of the documentation, the following code should return an intersection of the 2 maps performing addition on the values where the maps overlap.
#include <boost/itl/interval_map.hpp>
using namespace boost::itl;
int main( int argc, char * argv[] ) {
interval_map< int, float > map_1; interval_map< int, float > map_2;
map_1 & map_2;
return 0; }
I get a compile error on gcc 4.4.1 complaining about "invalid operands of types ‘float’ and ‘const float’ to binary ‘operator &’". Is this a bug or did I get the wrong end of the stick?
Found the culprit :) Although never actually called for this instantiation, interval_map< int, float >, the intersection functor is set to inplace_et and appears in the code that is called when map_1 & map_2; is applied. I have added partial instantiations for inplace_et<float>. This is a quickfix, but fully fuctional. The more proper fix will be done within the next days. You can update file https://svn.boost.org/svn/boost/sandbox/itl/boost/itl/functors.hpp from the sandbox to get the fix. Thanks, Joachim
