Member Enumeration Documentation

◆ anonymous enum

template<class MsgVer>

anonymous enum : bool

Enumerator
has_static_size	The message is statically-sized, not dynamically, so sizeof(the derived message-type) is the amount to copy, i.e. length() returns sizeof(the derived message-type).

Constructor & Destructor Documentation

◆ Header()

template<class MsgVer >

constexpr __stdcall isimud::exchanges::FIX::common::Header< MsgVer >::Header ( )

inlineconstexprnoexcept

Create a FIX message from an array of chars read from a socket or elsewhere.

In debug builds the validity of the FIX message is checked.

Parameters

b	The array of chars that must comprise a valid FIX message.

Definition at line 91 of file messages_impl.hpp.

Member Function Documentation

◆ find() [1/2]

template<class MsgVer >

template<FieldsFast field>

constexpr const field_str_range_t __fastcall isimud::exchanges::FIX::common::Header< MsgVer >::find ( ) const

inlineconstexprnoexcept

Determine if the specified tag is in the referenced message.

Parameters

field The field to be found. Note that the range must contain the field otherwise the behaviour shall be undefined.

Returns: True if the specified tag was found in the referenced message.

Definition at line 128 of file messages_impl.hpp.

◆ find() [2/2]

template<class MsgVer >

template<FieldsFast field>

constexpr field_str_range_t __fastcall isimud::exchanges::FIX::common::Header< MsgVer >::find ( )

inlineconstexprnoexcept

Determine if the specified tag is in the referenced message.

Parameters

field The field to be found. Note that the range must contain the field otherwise the behaviour shall be undefined.

Returns: True if the specified tag was found in the referenced message.

Definition at line 108 of file messages_impl.hpp.

◆ generate_checksum()

template<class MsgVer >

checksum_t isimud::exchanges::FIX::common::Header< MsgVer >::generate_checksum ( size_type body_len ) const

inlinenoexcept

Generate the checksum for the referenced FIX message.

Parameters

body_len The length of the body of the referenced FIX message.

Returns: The computed check sum.

Definition at line 163 of file messages_impl.hpp.

◆ is_checksum_valid()

template<class MsgVer >

constexpr bool isimud::exchanges::FIX::common::Header< MsgVer >::is_checksum_valid	(	size_type	body_len,
		const_pointer	start_of_checksum_value
	)		const

inlineconstexprnoexcept

Verify that the checksum of the referenced FIX message is valid.

Parameters

body_len	The length of the body of the referenced FIX message.
start_of_checksum_value	A pointer to that start of the checksum value embedded in the referenced FIX message.

Returns: True is the checksum of the referenced FIX message is valid, false otherwise.

Definition at line 174 of file messages_impl.hpp.

◆ is_valid()

template<class MsgVer >

constexpr bool isimud::exchanges::FIX::common::Header< MsgVer >::is_valid ( ) const

inlineconstexprnoexcept

Verify that the referenced FIX message is valid.

Returns: True is the referenced FIX message is valid, false otherwise.

Definition at line 180 of file messages_impl.hpp.

◆ length()

template<class MsgVer >

constexpr Header< MsgVer >::size_type isimud::exchanges::FIX::common::Header< MsgVer >::length ( ) const

inlineconstexprnoexcept

Determine the total size of the referenced message.

The referenced message must be valid.

Returns: The size of the whole the message, including the version, size (itself) and checksum fields.
