Member Function Documentation

get_control()

auto cycle_ptr::detail::vertex::get_control ( ) const -> intrusive_ptr< base_control >

noexcept

Read the target control block.

Returns

The target control block of this vertex.

reset()

auto cycle_ptr::detail::vertex::reset ( intrusive_ptr< base_control >  new_dst, bool  has_reference, bool  no_red_promotion  ) -> void

protected

Assign a new new_dst.

Assigns new_dst as the pointee of this vertex.

Parameters

new_dst	The destination of the edge. May be null.
has_reference	If set, new_dst has a reference count that will be consumed. (Ignored for null new_dst.)
no_red_promotion	If set, caller guarantees no red promotion is required. Note that this must be set, if has_reference is set. (Ignored for null new_dst.)

throw_if_owner_expired()

auto cycle_ptr::detail::vertex::throw_if_owner_expired ( ) const -> void

inlineprotected

Throw exception if owner is expired.

It is not allowed to read member pointers from an expired object.

Todo:

Create dedicated exception for this case.
