Re: [Boost-users] [iostream] Overloaded bitshift operators

28 Feb 2008

      On second thought, even though I've found the operators they don't do what I
expected them to do in my tests. So, I have the following stream, which is a
seekable device:

boost::iostreams::stream<MyStreamDevice> IOStream;

void foo()
{
    char data;
    IOStream >> data;
}

I expected here that MyStreamDevice::read() would be called with a request
for 1 byte, since the sizeof( data ) is 1 byte. I want my stream to act as
binary, so the bitshift operators should attempt to "fill" the right operand
with as much as it can. For longs, this would be 4 bytes for example.

Do I have to overload my own generic bitshift operators for this behavior or
does Boost.Iostreams supply some overloaded bitshift operators that provide
such functionality?

Sorry, I posted too early, I found the answer in the documentation. I was
looking around forever and I couldn't find it :)

Does the Boost.Iostreams library have overloaded bitshift operators?
That way I could do:
boost::iostreams::stream<myclass> theOutputStream;
theOutputStream << MyData;
