Detailed Description

\rst Holds a reference to a Python object (with reference counting)

Like handle, the object class is a thin wrapper around an arbitrary Python object (i.e. a PyObject * in Python's C API). In contrast to handle, it optionally increases the object's reference count upon construction, and it always* decreases the reference count when the object instance goes out of scope and is destructed. When using object instances consistently, it is much easier to get reference counting right at the first attempt. \endrst

Constructor & Destructor Documentation

◆ object() [1/5]

object::object ( )
default

◆ object() [2/5]

object::object ( const object o)
inline

Copy constructor; always increases the reference count.

Definition at line 374 of file pytypes.h.

◆ object() [3/5]

object::object ( object &&  other)
inlinenoexcept

Move constructor; steals the object from other and preserves its reference count.

Definition at line 376 of file pytypes.h.

◆ ~object()

object::~object ( )
inline

Destructor; automatically calls handle::dec_ref()

Definition at line 378 of file pytypes.h.

◆ object() [4/5]

object::object ( handle  h,
borrowed_t   
)
inline

Definition at line 449 of file pytypes.h.

◆ object() [5/5]

object::object ( handle  h,
stolen_t   
)
inline

Definition at line 450 of file pytypes.h.

Member Function Documentation

◆ cast() [1/3]

template<typename T >
T object::cast ( ) &&

◆ cast() [2/3]

template<typename T >
T object::cast

Definition at line 1293 of file cast.h.

◆ cast() [3/3]

template<>
void object::cast ( ) const &
inline

Definition at line 1301 of file cast.h.

◆ operator=() [1/2]

object& object::operator= ( const object other)
inline

Definition at line 391 of file pytypes.h.

◆ operator=() [2/2]

object& object::operator= ( object &&  other)
inlinenoexcept

Definition at line 404 of file pytypes.h.

◆ PYBIND11_DEPRECATED()

object::PYBIND11_DEPRECATED ( "Use reinterpret_borrow<object>() or reinterpret_steal<object>()"  )

◆ release()

handle object::release ( )
inline

\rst Resets the internal pointer to nullptr without decreasing the object's reference count. The function returns a raw handle to the original Python object. \endrst

Definition at line 385 of file pytypes.h.
