// This is a base class for QPDF Object Helper classes. Object helpers are classes that provide a
// convenient, higher-level API for working with specific types of QPDF objects. Object helpers are
// always initialized with a QPDFObjectHandle, and the underlying object handle can always be
// retrieved. The intention is that you may freely intermix use of object helpers with the
// underlying QPDF objects unless there is a specific comment in a specific helper method that says
// otherwise. The pattern of using helper objects was introduced to allow creation of higher level
// helper functions without polluting the public interface of QPDFObjectHandle.
