Hi,
First of all thanks very much for the ICL!
I'm using a boost::icl::interval_map with my own value type (struct V)
and I have a custom value combining logic by passing
boost::icl::inplace_et to the map and defining my own "operator&=" that
provides the logic implementation.
Now what happens is that my map ignores "m += make_pair(..., V())"
because the default-constructed value is considered neutral due to:
boost/icl/interval_base_map.hpp:
... interval_base_map<...>::_add(const segment_type& addend) {
typedef typename on_absorbtion<type,Combiner,
absorbs_identities<type>::value>::type on_absorbtion_;
...
const codomain_type& co_val = addend.second;
if(on_absorbtion_::is_absorbable(co_val))
return this->_map.end();
This 'if' returns without actually modifying the map. Is there some
public API that I can use to tell my map that it should not consider any
value 'absorbable'? And is it a good idea to change this?
Thank you,
Filip
