Detailed Description

template<typename T, typename Alloc>
class cycle_ptr::detail::control< T, Alloc >

Control block implementation for given type and allocator combination.

Extends base_control, adding specifics for creating and destroying T.

Template Parameters

T	The type of object managed by this control block.
Alloc	The allocator used to allocate storage for this control block.

Constructor & Destructor Documentation

control()

template<typename T , typename Alloc >

cycle_ptr::detail::control< T, Alloc >::control ( Alloc  alloc )

inline

Create control block.

Parameters

alloc

The allocator used to allocate space for this control block.

Member Function Documentation

instantiate()

template<typename T , typename Alloc >

template<typename... Args>

auto cycle_ptr::detail::control< T, Alloc >::instantiate ( Args &&...  args ) -> T*

inline

Instantiate the object managed by this control block.

Uses placement new to instantiate the object that is being managed.

Precondition

!this->under_construction

Postcondition

this->under_construction

Parameters

args	Arguments to pass to constructor of T.

Exceptions

...	if constructor of T throws.
