not1 doesn't work well with boost::mem_fn applied to shared_ptr, but you may
try
!boost::bind( &CEgg::IsHatched, _1 )
instead.
I tried the following:
bool SomeEggsHaveHatched()
{
tEggsVector basketOfEggs;
using boost::lambda::_1;
tEggsVector::const_iterator it = std::find_if(
basketOfEggs.begin(),
basketOfEggs.end(),
boost::bind( &CEgg::IsHatched, _1 ) );
bool bSomeEggsHaveHatched = ( it != basketOfEggs.end() );
return bSomeEggsHaveHatched;
}
but it won't compile, giving:
