Detailed Description

IOStream Class wrapper for C2paStream.

This class is used to wrap an input/output stream for use with the C2PA library.

Constructor & Destructor Documentation

CppIOStream() [1/3]

template<typename IOStream >

c2pa::CppIOStream::CppIOStream ( IOStream &  iostream )

inline

Construct an I/O stream wrapper from a std::iostream-derived object.

Template Parameters

IOStream

Type derived from std::iostream.

Parameters

iostream

The I/O stream to wrap (must be open and valid).

Exceptions

C2paException

if stream wrapper creation fails.

                                        {
            static_assert(std::is_base_of<std::iostream, IOStream>::value, "Stream must be derived from std::iostream");
            c_stream = c2pa_create_stream(reinterpret_cast<StreamContext *>(&iostream), reader, seeker, writer, flusher);
            if (c_stream == nullptr) {
                throw C2paException("Failed to create I/O stream wrapper: is stream open and valid?");
            }
