Re: [boost] [iostreams] bug: is_open() should be const

Hi,

[referring to latest CVS version]

in both class templates boost::iostreams::detail::direct_streambuf and boost::iostreams::detail::indirect_streambuf, member function is_open() is not declared const. However, boost::iostreams::stream<>::is_open() is declared const, so it won't compile as it calls one the former on a data member. Therefore, either all three members are declared const or none of them. The all-const approach makes more sense, IMHO.

My recollection is that all the is_open() functions should be const, so I'm inclined to change [in]direct_streambuf. Could you give me an example of something that won't currently compile, but should?

HTH,

Ganesh
