Function Documentation

get_frame_id() [1/2]

template<typename T , nullptr_t >

const std::string & autoware::common::helper_functions::message_field_adapters::get_frame_id ( const T &  msg )

noexcept

Get frame id from message. nullptr_t is used to prevent template ambiguity on SFINAE specializations. Provide a default value on specializations for a friendly API.

Template Parameters

T	Message type.

Parameters

msg

Message.

Returns

Frame id of the message.

get_frame_id() [2/2]

template<typename T , nullptr_t >

std::string & autoware::common::helper_functions::message_field_adapters::get_frame_id ( T &  msg )

noexcept

Get a reference to the frame id from message. nullptr_t is used to prevent template ambiguity on SFINAE specializations. Provide a default value on specializations for a friendly API.

Template Parameters

T	Message type.

Parameters

msg

Message.

Returns

Frame id of the message.

get_stamp() [1/3]

template<typename T , nullptr_t >

const TimeStamp& autoware::common::helper_functions::message_field_adapters::get_stamp ( const T &  msg )

noexcept

Get stamp from message. nullptr_t is used to prevent template ambiguity on SFINAE specializations. Provide a default value on specializations for a friendly API.

Template Parameters

T	Message type.

Parameters

msg

Message.

Returns

Frame id of the message.

get_stamp() [2/3]

template<typename T , nullptr_t >

TimeStamp & autoware::common::helper_functions::message_field_adapters::get_stamp ( T &  msg )

noexcept

Get a reference to the stamp from message. nullptr_t is used to prevent template ambiguity on SFINAE specializations. Provide a default value on specializations for a friendly API.

Template Parameters

T	Message type.

Parameters

msg

Message.

Returns

Frame id of the message.

get_stamp() [3/3]

template<class T , typename std::enable_if< HasHeader< T >::value, nullptr_t >::type = nullptr>

TimeStamp autoware::common::helper_functions::message_field_adapters::get_stamp ( const T &  msg )

noexcept

Get stamp from message. nullptr_t is used to prevent template ambiguity on SFINAE specializations. Provide a default value on specializations for a friendly API.

Template Parameters

T	Message type.

Parameters

msg

Message.

Returns

Frame id of the message.
