Python APT C++ API ================== The C++ API provides functions to create Python objects from C++ objects and to retrieve the C++ object stored in the Python object. An object may have another Python object as its owner and keeps its owner alive for its lifetime. Some objects require an owner of a specific type, while others require none. Refer to the sections below for details. The C++ API names use the name of the class in apt_pkg and are prefixed with Py. For each supported class, there is a _Type object, a _Check() function, a _CheckExact() function, a _FromCpp() and a _ToCpp() function. .. versionadded:: 0.7.100 Acquire (pkgAcquire) -------------------- .. cpp:var:: PyTypeObject PyAcquire_Type The type object for :class:`apt_pkg.Acquire` objects. .. cpp:function:: int PyAcquire_Check(PyObject *object) Check that the object *object* is an :class:`apt_pkg.Acquire` object, or a subclass thereof. .. cpp:function:: int PyAcquire_CheckExact(PyObject *object) Check that the object *object* is an :class:`apt_pkg.Acquire` object and no subclass thereof. .. cpp:function:: PyObject* PyAcquire_FromCpp(pkgAcquire *acquire, bool delete, PyObject *owner) Create a new :class:`apt_pkg.Acquire` object from the :cpp:type:`pkgAcquire` pointer given by the parameter *acquire*.
