Weak Reference Objects

There are two specific object types which directly implement weak references. The first is a simple reference object, and the second acts as a proxy for the original object as much as it can

• int PyWeakref_Check(PyObject *ob)
• int PyWeakref_CheckRef(PyObject *ob)
• int PyWeakref_CheckProxy(PyObject *ob)
• PyObject *PyWeakref_NewProxy(PyObject *ob, PyObject *callback)
• PyObject *PyWeakref_GetObject(PyObject *ref)
• PyObject *PyWeakref_GET_OBJECT(PyObject *ref)
• void PyObject_ClearWeakRefs(PyObject *object)
