Classes | |
class | Exiv2::TypeInfo |
Type information lookup functions. Implemented as a static class. More... | |
struct | Exiv2::DataBufRef |
Auxiliary type to enable copies and assignments, similar to std::auto_ptr_ref. See http://www.josuttis.com/libbook/auto_ptr.html for a discussion. More... | |
class | Exiv2::DataBuf |
