Detailed Description

template<typename BaseType, class RawAllocator>
class wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >

A deleter class that deallocates the memory of a derived type through a specified RawAllocator.

It can only be created from a allocator_deallocator and thus must only be used for smart pointers initialized by derived-to-base conversion of the pointer.

Member Typedef Documentation

allocator_type

template<typename BaseType , class RawAllocator >

using wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >::allocator_type = typename allocator_reference<RawAllocator>::allocator_type

value_type

template<typename BaseType , class RawAllocator >

using wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >::value_type = BaseType

Constructor & Destructor Documentation

allocator_polymorphic_deallocator()

template<typename BaseType , class RawAllocator >

template<typename T >

wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >::allocator_polymorphic_deallocator ( allocator_deallocator< T, RawAllocator > dealloc )

inline

Effects:

Creates it from a deallocator for a derived type. It will deallocate the memory as if done by the derived type.

Member Function Documentation

get_allocator()

template<typename BaseType , class RawAllocator >

auto wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >::get_allocator ( ) const -> decltype(std::declval<allocator_reference<allocator_type>>().get_allocator())

inlinenoexcept

Returns:

The reference to the allocator. It has the same type as the call to allocator_reference::get_allocator().

operator()()

template<typename BaseType , class RawAllocator >

void wpi::memory::allocator_polymorphic_deallocator< BaseType, RawAllocator >::operator() ( value_type * pointer )

inlinenoexcept

Effects:

Deallocates the memory given to it. Calls deallocate_node(pointer, size, alignment) on the referenced allocator object, where size and alignment are the values of the type it was created with.
