Hello all:
Hoping someone might help with a simple problem; how I might call a
member on a boost::bind placeholder, see below ...
#include <list>
class Xtype
{
public:
Xtype(int v)
: value_(v)
{
}
int the_value() const
{
return this->value_;
}
private:
int value_;
};
template <typename Predicate>
class Excise
{
public:
void operator()(std::list<Xtype>& li) const
{
li.remove_if(boost::bind(Predicate(), ::_1, 10));
}
};
... what I really want is something more like [, note the call of
Xtype::this_value() ]:
void operator()(std::list<Xtype>& li) const
{
li.remove_if(boost::bind(Predicate(), ::_1.the_value(), 10));
}
But how do I achieve that (, if at all possible); as seemingly
::_1.the_value() is illegal/invalid code ?
Thanks in advance,
-- Manfred
