bool-fn-constant clj

(bool-fn-constant item)

bool-fn-table clj

Py_DecRef clj

(Py_DecRef py-obj)

Decrement the refference count on an object

Py_IncRef clj

(Py_IncRef py-obj)

Increment the reference count on an object

PyCallable_Check clj

(PyCallable_Check pyobj)

Determine if the object o is callable. Return 1 if the object is callable and 0 otherwise. This function always succeeds.

PyObject_Call clj

(PyObject_Call callable args kwargs)

Return value: New reference.

Call a callable Python object callable, with arguments given by the tuple args, and named arguments given by the dictionary kwargs.

args must not be NULL, use an empty tuple if no arguments are needed. If no named arguments are needed, kwargs can be NULL.

Returns the result of the call on success, or NULL on failure.

This is the equivalent of the Python expression: callable(*args, **kwargs).

PyObject_CallObject clj

(PyObject_CallObject callable args)

Return value: New reference.

Call a callable Python object callable, with arguments given by the tuple args. If no arguments are needed, then args can be NULL.

Returns the result of the call on success, or NULL on failure.

This is the equivalent of the Python expression: callable(*args).

PyObject_DelAttr clj

(PyObject_DelAttr pyobj attr-name)

Delete attribute named attr_name, for object o. Returns -1 on failure. This is the equivalent of the Python statement del o.attr_name.

PyObject_DelAttrString clj

(PyObject_DelAttrString pyobj attr-name)

Delete attribute named attr_name, for object o. Returns -1 on failure. This is the equivalent of the Python statement del o.attr_name.

PyObject_DelItem clj

(PyObject_DelItem o key)

Remove the mapping for the object key from the object o. Return -1 on failure. This is equivalent to the Python statement del o[key].

PyObject_Dir clj

(PyObject_Dir o)

Return value: New reference.

This is equivalent to the Python expression dir(o), returning a (possibly empty) list of strings appropriate for the object argument, or NULL if there was an error. If the argument is NULL, this is like the Python dir(), returning the names of the current locals; in this case, if no execution frame is active then NULL is returned but PyErr_Occurred() will return false.

PyObject_GenericGetAttr clj

(PyObject_GenericGetAttr pyobj attr-name)

Return value: New reference.

Generic attribute getter function that is meant to be put into a type object’s tp_getattro slot. It looks for a descriptor in the dictionary of classes in the object’s MRO as well as an attribute in the object’s dict (if present). As outlined in Implementing Descriptors, data descriptors take preference over instance attributes, while non-data descriptors don’t. Otherwise, an AttributeError is raised.

PyObject_GenericGetDict clj

(PyObject_GenericGetDict pyobj context)

Return value: New reference.

A generic implementation for the getter of a dict descriptor. It creates the dictionary if necessary.

New in version 3.3.

PyObject_GenericSetAttr clj

(PyObject_GenericSetAttr pyobj attr-name v)

Generic attribute setter and deleter function that is meant to be put into a type object’s tp_setattro slot. It looks for a data descriptor in the dictionary of classes in the object’s MRO, and if found it takes preference over setting or deleting the attribute in the instance dictionary. Otherwise, the attribute is set or deleted in the object’s dict (if present). On success, 0 is returned, otherwise an AttributeError is raised and -1 is returned.

PyObject_GenericSetDict clj

(PyObject_GenericSetDict pyobj context)

A generic implementation for the setter of a dict descriptor. This implementation does not allow the dictionary to be deleted.

New in version 3.3.

PyObject_GetAttr clj

(PyObject_GetAttr pyobj attr-name)

Return value: New reference.

Retrieve an attribute named attr_name from object o. Returns the attribute value on success, or NULL on failure. This is the equivalent of the Python expression o.attr_name.

PyObject_GetAttrString clj

(PyObject_GetAttrString pyobj attr-name)

Return value: New reference.

Retrieve an attribute named attr_name from object o. Returns the attribute value on success, or NULL on failure. This is the equivalent of the Python expression o.attr_name.

PyObject_GetItem clj

(PyObject_GetItem o key)

Return value: New reference.

Return element of o corresponding to the object key or NULL on failure. This is the equivalent of the Python expression o[key].

PyObject_GetIter clj

(PyObject_GetIter o)

Return value: New reference.

This is equivalent to the Python expression iter(o). It returns a new iterator for the object argument, or the object itself if the object is already an iterator. Raises TypeError and returns NULL if the object cannot be iterated.

PyObject_HasAttr clj

(PyObject_HasAttr pyobj attr-name)

Returns 1 if o has the attribute attr_name, and 0 otherwise. This is equivalent to the Python expression hasattr(o, attr_name). This function always succeeds.

Note that exceptions which occur while calling getattr() and getattribute() methods will get suppressed. To get error reporting use PyObject_GetAttr() instead.

PyObject_HasAttrString clj

(PyObject_HasAttrString pyobj attr-name)

Returns 1 if o has the attribute attr_name, and 0 otherwise. This is equivalent to the Python expression hasattr(o, attr_name). This function always succeeds.

Note that exceptions which occur while calling getattr() and getattribute() methods and creating a temporary string object will get suppressed. To get error reporting use Pointer_GetAttrString() instead.

PyObject_Hash clj

(PyObject_Hash o)

Compute and return the hash value of an object o. On failure, return -1. This is the equivalent of the Python expression hash(o).

Changed in version 3.2: The return type is now Py_hash_t. This is a signed integer the same size as Py_ssize_t.

PyObject_IsTrue clj

(PyObject_IsTrue py-obj)

Returns 1 if the object o is considered to be true, and 0 otherwise. This is equivalent to the Python expression not not o. On failure, return -1.

PyObject_Length clj

(PyObject_Length py-obj)

Return the length of object o. If the object o provides either the sequence and mapping protocols, the sequence length is returned. On error, -1 is returned. This is the equivalent to the Python expression len(o).

PyObject_Not clj

(PyObject_Not py-obj)

Returns 0 if the object o is considered to be true, and 1 otherwise. This is equivalent to the Python expression not o. On failure, return -1.

PyObject_Repr clj

(PyObject_Repr py_obj)

Return value: New reference.

Compute a string representation of object o. Returns the string representation on success, NULL on failure. This is the equivalent of the Python expression repr(o). Called by the repr() built-in function.

Changed in version 3.4: This function now includes a debug assertion to help ensure that it does not silently discard an active exception.

PyObject_RichCompare clj

(PyObject_RichCompare o1 o2 opid)

Return value: New reference.

Compare the values of o1 and o2 using the operation specified by opid, which must be one of Py_LT, Py_LE, Py_EQ, Py_NE, Py_GT, or Py_GE, corresponding to <, <=, ==, !=,

, or >= respectively. This is the equivalent of the Python expression o1 op o2, where op is the operator corresponding to opid. Returns the value of the comparison on success, or NULL on failure.

PyObject_RichCompareBool clj

(PyObject_RichCompareBool o1 o2 opid)

Compare the values of o1 and o2 using the operation specified by opid, which must be one of Py_LT, Py_LE, Py_EQ, Py_NE, Py_GT, or Py_GE, corresponding to <, <=, ==, !=, >, or >= respectively. Returns -1 on error, 0 if the result is false, 1 otherwise. This is the equivalent of the Python expression o1 op o2, where op is the operator corresponding to opid.

Note

If o1 and o2 are the same object, PyObject_RichCompareBool() will always return 1 for Py_EQ and 0 for Py_NE.

PyObject_SetAttr clj

(PyObject_SetAttr pyobj attr-name v)

Set the value of the attribute named attr_name, for object o, to the value v. Raise an exception and return -1 on failure; return 0 on success. This is the equivalent of the Python statement o.attr_name = v.

If v is NULL, the attribute is deleted, however this feature is deprecated in favour of using PyObject_DelAttr().

PyObject_SetAttrString clj

(PyObject_SetAttrString pyobj attr-name v)

Set the value of the attribute named attr_name, for object o, to the value v. Raise an exception and return -1 on failure; return 0 on success. This is the equivalent of the Python statement o.attr_name = v.

If v is NULL, the attribute is deleted, however this feature is deprecated in favour of using PyObject_DelAttrString().

PyObject_SetItem clj

(PyObject_SetItem o key v)

Map the object key to the value v. Raise an exception and return -1 on failure; return 0 on success. This is the equivalent of the Python statement o[key] = v.

PyObject_Str clj

(PyObject_Str py-obj)

Return value: New reference.

Compute a string representation of object o. Returns the string representation on success, NULL on failure. This is the equivalent of the Python expression str(o). Called by the str() built-in function and by the print statement.

PyObject_Type clj

(PyObject_Type py-obj)

Return value: New reference.

When o is non-NULL, returns a type object corresponding to the object type of object o. On failure, raises SystemError and returns NULL. This is equivalent to the Python expression type(o). This function increments the reference count of the return value. There’s really no reason to use this function instead of the common expression o->ob_type, which returns a pointer of type PyTypeObject*, except when the incremented reference count is needed.
