const_buffer_sequence()

std::vector< as::const_buffer > async_mqtt::property_variant::const_buffer_sequence ( ) const

inline

Create const buffer sequence. it is for boost asio APIs.

Returns

const buffer sequence

get() [1/2]

template<typename T >

decltype(auto) async_mqtt::property_variant::get ( )

inline

Get by type. If not match, then throw std::bad_variant_access exception.

Returns

actual packet

get() [2/2]

template<typename T >

decltype(auto) async_mqtt::property_variant::get ( ) const

inline

Get by type. If not match, then throw std::bad_variant_access exception.

Returns

actual packet

get_if() [1/2]

template<typename T >

decltype(auto) async_mqtt::property_variant::get_if ( )

inline

Get by type pointer.

Returns

actual packet pointer. If not match then return nullptr.

get_if() [2/2]

template<typename T >

decltype(auto) async_mqtt::property_variant::get_if ( ) const

inline

Get by type pointer.

Returns

actual packet pointer. If not match then return nullptr.

id()

property::id async_mqtt::property_variant::id ( ) const

inline

Get property_id.

Returns

property_id

num_of_const_buffer_sequence()

std::size_t async_mqtt::property_variant::num_of_const_buffer_sequence ( ) const

inline

Get number of element of const_buffer_sequence.

Returns

number of element of const_buffer_sequence

size()

std::size_t async_mqtt::property_variant::size ( ) const

inline

Get packet size.

Returns

packet size

auto async_mqtt::property_variant::visit ( Func && func ) &

inline

visit to variant

Parameters

func	Visitor function

visit() [2/3]

template<typename Func >

auto async_mqtt::property_variant::visit ( Func && func ) &&

inline
