Member Function Documentation

◆ matches()

bool caf::type_erased_tuple::matches	(	size_t	pos,
		uint16_t	nr,
		const std::type_info *	ptr
	)		const

noexcept

Checks whether the type of the stored value at position pos matches type number n and run-time type information p.

◆ move_if_unshared()

template<class T >

T caf::type_erased_tuple::move_if_unshared ( size_t pos )

Convenience function for moving a value out of the tuple if it is unshared.

Returns a copy otherwise.

◆ shared()

virtual bool caf::type_erased_tuple::shared ( ) const

virtualnoexcept

Returns whether multiple references to this tuple exist.

The default implementation returns false.

Reimplemented in caf::message.

◆ type()

virtual rtti_pair caf::type_erased_tuple::type ( size_t pos ) const

pure virtualnoexcept

Returns the type number and std::type_info object for the element at position pos.

Implemented in caf::empty_type_erased_tuple, and caf::message.
