In that case you would be well catered for by.....
class buffered_observer : public observer
{
std::stringstream write_stream_;
protected:
std::ostream & out() { return write_stream_; }
public:
std::istream & write_stream()
{
return write_stream_;
}
};
Note: I am assuming that the multiplexor will not reenter the observer
on another thread during an on_xxx call
Now your example could become
class my_observer : public buffered_observer
{
public:
void on_connect()
{
...
out() << "Hello World" << std::flush;
}
};
I will take an ostream over writen any day.
