Detailed Description

Represents a parsed incoming FIX message.

Always call has_tag() or has_repeating_group_tag() before accessing values.

Repeating groups are handled separately via IncomingFixRepeatingGroups and accessed through dedicated APIs.

get_repeating_group_tag_value_as()

template<typename T >

T llfix::IncomingFixMessage::get_repeating_group_tag_value_as ( uint32_t  tag, std::size_t  index, std::size_t  decimal_points = 0  ) const

inline

Retrieves a repeating group tag value converted to the requested type.

Template Parameters

T	Target return type.

Parameters

tag	FIX tag number.
index	Repeating group index (0-based).
decimal_points	Number of decimal places (required for floating-point and FixedPoint).

Returns

Tag value converted to type T.

Note

Supported types:

• std::string_view
• std::string
• char
• bool
• integral types
• floating-point types
• FixedPoint

get_tag_value_as()

template<typename T >

T llfix::IncomingFixMessage::get_tag_value_as ( uint32_t  tag, std::size_t  decimal_points = 0  ) const

inline

Retrieves a FIX tag value converted to the requested type.

Template Parameters

T	Target return type.

Parameters

tag	FIX tag number.
decimal_points	Number of decimal points (required for floating-point and FixedPoint types).

Returns

Tag value converted to type T.

Note

Supported types:

• std::string_view
• std::string
• char
• bool
• integral types
• floating-point types
• FixedPoint

has_repeating_group_tag()

bool llfix::IncomingFixMessage::has_repeating_group_tag ( uint32_t  tag ) const

inline

Checks whether a repeating group tag exists.

Parameters

tag	FIX tag number belonging to a repeating group.

Returns

true if the tag exists in the repeating group storage, false otherwise.

has_tag()

bool llfix::IncomingFixMessage::has_tag ( uint32_t  tag ) const

inline

Checks whether a FIX tag exists and is valid.

Parameters

tag	FIX tag number.

Returns

true if the tag exists, false otherwise.

to_string()

std::string llfix::IncomingFixMessage::to_string ( ) const

inline

Serialises the FIX message into a human-readable string.

The output is formatted as:

• Header fields first (8, 9, 35, 34, 49, 52, 56)
• Body fields (excluding header and trailer)
• Repeating group fields
• Trailer field (10)

Fields are separated by the '|' character instead of SOH.

Returns

A string representation of the FIX message
