Asignación de objetos en el montículo¶
-
PyObject *_PyObject_New(PyTypeObject *type)¶
- Return value: New reference.
-
PyVarObject *_PyObject_NewVar(PyTypeObject *type, Py_ssize_t size)¶
- Return value: New reference.
-
PyObject *PyObject_Init(PyObject *op, PyTypeObject *type)¶
- Return value: Borrowed reference. Part of the Stable ABI.
Initialize a newly allocated object op with its type and initial reference. Returns the initialized object. If type indicates that the object participates in the cyclic garbage detector, it is added to the detector’s set of observed objects. Other fields of the object are not affected.
-
PyVarObject *PyObject_InitVar(PyVarObject *op, PyTypeObject *type, Py_ssize_t size)¶
- Return value: Borrowed reference. Part of the Stable ABI.
Esto hace todo lo que
PyObject_Init()
hace, y también inicializa la información de longitud para un objeto de tamaño variable.
-
PyObject_New(TYPE, typeobj)¶
Allocate a new Python object using the C structure type TYPE and the Python type object typeobj (
PyTypeObject*
). Fields not defined by the Python object header are not initialized. The caller will own the only reference to the object (i.e. its reference count will be one). The size of the memory allocation is determined from thetp_basicsize
field of the type object.
-
PyObject_NewVar(TYPE, typeobj, size)¶
Allocate a new Python object using the C structure type TYPE and the Python type object typeobj (
PyTypeObject*
). Fields not defined by the Python object header are not initialized. The allocated memory allows for the TYPE structure plus size (Py_ssize_t
) fields of the size given by thetp_itemsize
field of typeobj. This is useful for implementing objects like tuples, which are able to determine their size at construction time. Embedding the array of fields into the same allocation decreases the number of allocations, improving the memory management efficiency.
-
void PyObject_Del(void *op)¶
Same as
PyObject_Free()
.
-
PyObject _Py_NoneStruct¶
Objeto que es visible en Python como
None
. Esto solo se debe acceder utilizando el macroPy_None
, que se evalúa como un puntero a este objeto.
