6.4 Mapping Protocol
- int PyMapping_Check(PyObject *o)
-
Return 1 if the object provides mapping protocol, and 0
otherwise.
This function always succeeds.
- int PyMapping_Length(PyObject *o)
-
Returns the number of keys in object o on success, and -1
on failure. For objects that do not provide sequence protocol,
this is equivalent to the Python expression "len(o)".
- int PyMapping_DelItemString(PyObject *o, char *key)
-
Remove the mapping for object key from the object o.
Return -1 on failure. This is equivalent to
the Python statement "del o[key]".
- int PyMapping_DelItem(PyObject *o, PyObject *key)
-
Remove the mapping for object key from the object o.
Return -1 on failure. This is equivalent to
the Python statement "del o[key]".
- int PyMapping_HasKeyString(PyObject *o, char *key)
-
On success, return 1 if the mapping object has the key key
and 0 otherwise. This is equivalent to the Python expression
"o.has_key(key)".
This function always succeeds.
- int PyMapping_HasKey(PyObject *o, PyObject *key)
-
Return 1 if the mapping object has the key key and
0 otherwise. This is equivalent to the Python expression
"o.has_key(key)".
This function always succeeds.
- PyObject* PyMapping_Keys(PyObject *o)
-
On success, return a list of the keys in object o. On
failure, return NULL. This is equivalent to the Python
expression "o.keys()".
- PyObject* PyMapping_Values(PyObject *o)
-
On success, return a list of the values in object o. On
failure, return NULL. This is equivalent to the Python
expression "o.values()".
- PyObject* PyMapping_Items(PyObject *o)
-
On success, return a list of the items in object o, where
each item is a tuple containing a key-value pair. On
failure, return NULL. This is equivalent to the Python
expression "o.items()".
- int PyMapping_Clear(PyObject *o)
-
Make object o empty. Returns 1 on success and 0
on failure. This is equivalent to the Python statement
"for key in o.keys(): del o[key]".
- PyObject* PyMapping_GetItemString(PyObject *o, char *key)
-
Return element of o corresponding to the object key or
NULL on failure. This is the equivalent of the Python expression
"o[key]".
- PyObject* PyMapping_SetItemString(PyObject *o, char *key, PyObject *v)
-
Map the object key to the value v in object o.
Returns -1 on failure. This is the equivalent of the Python
statement "o[key] = v".
