Detailed Description

Output stream OStream wrapper for C2paStream.

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

Constructor & Destructor Documentation

CppOStream() [1/3]

template<typename OStream >

c2pa::CppOStream::CppOStream ( OStream &  ostream )

inlineexplicit

Construct an output stream wrapper from a std::ostream-derived object.

Template Parameters

OStream

Type derived from std::ostream.

Parameters

ostream

The output stream to wrap (must be open and valid).

Exceptions

C2paException

if stream wrapper creation fails.

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