Detailed Description

FIX message builder and encoder for outbound messages.

Member Function Documentation

get_sending_time()

std::string llfix::OutgoingFixMessage::get_sending_time ( )

inline

Returns the currently cached tag 52 (SendingTime) value.

Returns

SendingTime as a string.

set_binary_tag()

template<FixMessageComponent component = FixMessageComponent::BODY>

void llfix::OutgoingFixMessage::set_binary_tag ( uint32_t  tag, const char *  buffer, std::size_t  data_length  )

inline

Appends a FIX tag using the provided buffer with raw data.

Template Parameters

component

FIX message component to append to (default: FixMessageComponent::BODY)

Parameters

tag	FIX tag number representing a binary field
buffer	start address of buffer that hold raw/binary data
data_length	length of buffer

set_msg_type() [1/2]

void llfix::OutgoingFixMessage::set_msg_type ( char  c )

inline

Sets FIX MsgType (tag 35) using a single character.

This overload is intended for FIX message types represented by a single character (e.g. 'D', '8', '0').

Parameters

c	FIX MsgType character

set_msg_type() [2/2]

void llfix::OutgoingFixMessage::set_msg_type ( std::string_view  buffer )

inline

Sets FIX MsgType (tag 35) using a string view.

Supports multi-character FIX message types (e.g. "AE", "XLR").

Parameters

buffer

String view containing the message type

Precondition

Maximum buffer length is 4 characters

set_tag()

template<FixMessageComponent component = FixMessageComponent::BODY, typename T >

void llfix::OutgoingFixMessage::set_tag ( uint32_t  tag, T  val, std::size_t  decimal_points = 0  )

inline

Appends a FIX tag to the specified message component.

Encodes the supplied value into an internal FixString and appends it to the selected FIX message component (HEADER, BODY, or TRAILER).

Supported Value Types

• const char*
• std::string
• std::string_view
• char
• bool (Y/N)
• FixedPoint
• Integral types (signed / unsigned)
• Floating-point types (requires decimal_points)

Template Parameters

component	FIX message component to append to (default: FixMessageComponent::BODY)
T	Value type to encode

Parameters

tag	FIX tag number
val	Value to encode
decimal_points	Number of decimal places for floating-point values

set_timestamp_tag()

template<FixMessageComponent component = FixMessageComponent::BODY>

void llfix::OutgoingFixMessage::set_timestamp_tag ( uint32_t  tag )

inline

Appends a FIX timestamp tag using the current session time.

Encodes the current timestamp once per message using the session’s configured sub-second precision and reuses it for all timestamp tags within the same message.

Template Parameters

component

FIX message component to append to (default: FixMessageComponent::BODY)

Parameters

tag	FIX tag number representing a timestamp field
