Detailed Description

template<typename T, typename Allocator = std::allocator<void>>
struct asio::associated_allocator< T, Allocator >

Traits type used to obtain the allocator associated with an object.

A program may specialise this traits type if the T template parameter in the specialisation is a user-defined type. The template parameter Allocator shall be a type meeting the Allocator requirements.

Specialisations shall meet the following requirements, where t is a const reference to an object of type T, and a is an object of type Allocator.

Provide a nested typedef type that identifies a type meeting the Allocator requirements.

Provide a noexcept static member function named get, callable as get(t) and with return type type.

Provide a noexcept static member function named get, callable as get(t,a) and with return type type.

Member Typedef Documentation

◆ type

template<typename T, typename Allocator = std::allocator<void>>

typedef detail::associated_allocator_impl<T, Allocator>::type asio::associated_allocator< T, Allocator >::type

If T has a nested type allocator_type, T::allocator_type.

Otherwise Allocator.

Member Function Documentation

◆ get()

template<typename T, typename Allocator = std::allocator<void>>

static type asio::associated_allocator< T, Allocator >::get	(	const T &	t,
		const Allocator &	a = `Allocator()`
	)

inlinestatic

If T has a nested type allocator_type, returns t.get_allocator().

Otherwise returns a.
