Before rolling my own, does boost have a facility to stream out an iterator
range without the dangling delimiter at the end? For example
std::ostream& operator<<( std::ostream& s, const MyClass& aC )
{
const std::string lDelim( "," );
std::vector<int> lInts;
lInts.push_back(1);
lInts.push_back(2);
lInts.push_back(3);
std::ostream_iterator<int> lItr( s, lDelim.c_str() );
std::copy( lInts.begin(), lInts.end(), lItr );
}
yields:
1,2,3,
I'm thinking something like the following usage would be nice:
s << range_streamer( lInts.begin(), lInts.end(), "{", "," "}" );
yielding:
{1,2,3}
Any thoughts?
