-/**
- * \class IPAInterfaceWrapper
- * \brief Wrap an IPAInterface and expose it as an ipa_context
- *
- * This class implements the ipa_context API based on a provided IPAInterface.
- * It helps IPAs that implement the IPAInterface API to provide the external
- * ipa_context API.
- *
- * To use the wrapper, an IPA module simple creates a new instance of its
- * IPAInterface implementation, and passes it to the constructor of the
- * IPAInterfaceWrapper. As IPAInterfaceWrapper inherits from ipa_context, the
- * constructed wrapper can then be directly returned from the IPA module's
- * ipaCreate() function.
- *
- * \code{.cpp}
- * class MyIPA : public IPAInterface
- * {
- * ...
- * };
- *
- * struct ipa_context *ipaCreate()
- * {
- * return new IPAInterfaceWrapper(std::make_unique<MyIPA>());
- * }
- * \endcode
- *
- * The wrapper takes ownership of the IPAInterface and will automatically
- * delete it when the wrapper is destroyed.
