opaque<>
registers itself as a converter from Python objects to pointers to undefined
types and vice versa.
namespace boost { namespace python { template<class Pointee> struct opaque { opaque(); }; }}
opaque();
* Registers the instance as a lvalue_from_pytype
converter
from Python objects into opaque pointers. The Python Objects created
are named after the type pointed to by the opaque pointer being wrapped.
* Registers the instance as a to_python_converter
from
opaque pointers to Python objects.

---|---|
If there is already an instance registered by another module, this instance doesn't try to register again in order to avoid warnings about multiple registrations. |
This macro must be used to define specializations of the type_id
function which can't be
instantiated for incomplete types.

---|---|
The macro must be invoked in every translation unit which uses the opaque converter. |
