allocator_polymorphic_deleter< BaseType, RawAllocator > Class Template Reference

Detailed Description

template<typename BaseType, class RawAllocator>
class foonathan::memory::allocator_polymorphic_deleter< BaseType, RawAllocator >

Similar to allocator_polymorphic_deallocator but calls the destructors of the object.

Otherwise behaves the same.

Note

It has a relatively high space overhead, so only use it if you have to.

Constructors

allocator_polymorphic_deleter() [1/2]

template<typename BaseType, class RawAllocator>

allocator_polymorphic_deleter ( )

defaultnoexcept

Effects:

Creates it without any associated allocator. The deleter must not be used if that is the case.

Notes:

This functions is useful if you have want to create an empty smart pointer without giving it an allocator.

allocator_polymorphic_deleter() [2/2]

template<typename BaseType, class RawAllocator>

template<typename T>

allocator_polymorphic_deleter

(

allocator_deleter< T, RawAllocator >

deleter

)

Effects:

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

Member Functions

operator()()

template<typename BaseType, class RawAllocator>

void operator() ( value_type * pointer )

noexcept

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.

get_allocator()

template<typename BaseType, class RawAllocator>

auto get_allocator ( ) const -> decltype(std::declval<allocator_reference<allocator_type>>().get_allocator())

noexcept

Returns:

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