std::string detail::lexer< BasicJsonType, InputAdapterType >::get_token_string ( ) const

return the last read token (for errors only). Will never contain EOF (an arbitrary value that is not a valid char value, often -1), because 255 may legitimately occur. May contain NUL, which should be escaped.
