cast_op_type

template<typename T >

using cast_op_type = conditional_t<std::is_pointer<remove_reference_t<T> >::value, typename std::add_pointer<intrinsic_t<T> >::type, typename std::add_lvalue_reference<intrinsic_t<T> >::type>

Determine suitable casting operator for pointer-or-lvalue-casting type casters. The type caster needs to provide operator T*() and operator T&() operators.

If the type supports moving the value away via an operator T&&() && method, it should use movable_cast_op_type instead.

Definition at line 808 of file type_caster_base.h.

movable_cast_op_type

template<typename T >

using movable_cast_op_type = conditional_t<std::is_pointer<typename std::remove_reference<T>::type>::value, typename std::add_pointer<intrinsic_t<T> >::type, conditional_t<std::is_rvalue_reference<T>::value, typename std::add_rvalue_reference<intrinsic_t<T> >::type, typename std::add_lvalue_reference<intrinsic_t<T> >::type> >

Determine suitable casting operator for a type caster with a movable value. Such a type caster needs to provide operator T*(), operator T&(), and operator T&&() &&. The latter will be called in appropriate contexts where the value can be moved rather than copied.

These operator are automatically provided when using the PYBIND11_TYPE_CASTER macro.

Function Documentation

all_type_info()

const std::vector<detail::type_info *>& all_type_info ( PyTypeObject *  type )

inline

Extracts vector of type_info pointers of pybind-registered roots of the given Python type. Will be just 1 pybind type for the Python type of a pybind-registered class, or for any Python-side derived class that uses single inheritance. Will contain as many types as required for a Python class that uses multiple inheritance to inherit (directly or indirectly) from multiple pybind-registered classes. Will be empty if neither the type nor any base classes are pybind-registered.

The value is cached for the lifetime of the Python type.

Definition at line 169 of file type_caster_base.h.

all_type_info_get_cache()

std::pair<decltype(internals::registered_types_py)::iterator, bool> all_type_info_get_cache ( PyTypeObject *  type )

	)

Definition at line 240 of file type_caster_base.h.

get_global_type_info()

detail::type_info* get_global_type_info ( const std::type_index &  tp )

inline

Definition at line 205 of file type_caster_base.h.

get_local_type_info()

detail::type_info* get_local_type_info ( const std::type_index &  tp )

inline

Definition at line 196 of file type_caster_base.h.

get_object_handle()

PYBIND11_NOINLINE handle get_object_handle	(	const void *	ptr,
		const detail::type_info *	type
	)

Definition at line 473 of file type_caster_base.h.

get_thread_state_unchecked()

PyThreadState* get_thread_state_unchecked ( )

inline

Definition at line 486 of file type_caster_base.h.

get_type_handle()

PYBIND11_NOINLINE handle get_type_handle	(	const std::type_info &	tp,
		bool	throw_if_missing
	)

Definition at line 234 of file type_caster_base.h.

get_type_info() [1/2]

PYBIND11_NOINLINE detail::type_info* get_type_info	(	const std::type_index &	tp,
		bool	throw_if_missing = false
	)

Return the type info for a given C++ type; on lookup failure can either throw or return nullptr.

Definition at line 216 of file type_caster_base.h.

get_type_info() [2/2]

PYBIND11_NOINLINE detail::type_info* get_type_info

(

PyTypeObject *

type

)

Gets a single pybind11 type info for a python type. Returns nullptr if neither the type nor any ancestors are pybind11-registered. Throws an exception if there are multiple bases–use all_type_info instead if you want to support multiple bases.

Definition at line 184 of file type_caster_base.h.

isinstance_generic()

PYBIND11_NOINLINE bool isinstance_generic	(	handle	obj,
		const std::type_info &	tp
	)

keep_alive_impl()

void keep_alive_impl	(	handle	nurse,
		handle	patient
	)

Definition at line 2224 of file pybind11.h.

make_new_instance()

PyObject* make_new_instance ( PyTypeObject *  type )

inline

Instance creation function for all pybind11 types. It allocates the internal instance layout for holding C++ objects and holders. Allocation is done lazily (the first time the instance is cast to a reference or pointer), and initialization is done by an __init__ function.

Definition at line 349 of file class.h.

type_info_description()
