Classes

Class template opaque<P>

opaque<> registers itself as a converter from Python objects to pointers to undefined types and vice versa.

Class template opaque synopsis

namespace boost { namespace python
{
    template<class Pointee>
    struct opaque
    {
        opaque();
    };
}}

Class template opaque constructor

opaque();
Effects:

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.

Note

Normally only a single instance of this class is created for every Pointee.

Macros

Macro BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(Pointee)

This macro must be used to define specializations of the type_id function which can't be instantiated for incomplete types.

Note

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