Variable Documentation

custom_storageType

const MessageStorageType Engine::custom_storageType = MessageStorageType::custom()

Warning

This instance is provided for backward compatibility and is deprecated.

default_storageType

const MessageStorageType Engine::default_storageType = MessageStorageType::default_()

Configurable from engine.properties.

INVALID_PARSER_ID

ParserID const Engine::INVALID_PARSER_ID = 0

static

Invalid ParserID.

INVALID_PROTOCOL_ID

ProtocolID const Engine::INVALID_PROTOCOL_ID = INVALID_PARSER_ID

static

Invalid ProtocolID.

Deprecated

Use INVALID_PARSER_ID instead.

invalid_storageType

const MessageStorageType Engine::invalid_storageType = MessageStorageType::invalid()

Special instance representing incorrect storage type.

MINIMUM_PARSER_COUNT

ParserID const Engine::MINIMUM_PARSER_COUNT = 100

static

A minimum amount of parsers that can be configured.

null_storageType

const MessageStorageType Engine::null_storageType = MessageStorageType::builtin(BuiltinMessageStorage::Null)

Simple storage, that does not store anything - fast.

persistent_storageType

const MessageStorageType Engine::persistent_storageType = MessageStorageType::builtin(BuiltinMessageStorage::Persistent)

File storage - slow and safe.

persistentMM_storageType

const MessageStorageType Engine::persistentMM_storageType = MessageStorageType::builtin(BuiltinMessageStorage::PersistentMM)

Memory mapped file storage - fast and safe.

splitPersistent_storageType

const MessageStorageType Engine::splitPersistent_storageType = MessageStorageType::builtin(BuiltinMessageStorage::SplitPersistent)

Sliced file storage - fast and safe.

SplitStorage stores messages to the file of fixed size. If size of the file has reached the limit, storage closes file and creates new one. It allows to allocate storage on the RAM drive and move chunks of the storage to HDD in parallel. RAM drive should be connected to power supply to avoid data loss.

TOTAL_PARSER_ID_COUNT

ParserID const Engine::TOTAL_PARSER_ID_COUNT = MINIMUM_PARSER_COUNT

static

Last valid FIX parser identifier.

Deprecated

Use MaximumParsersAllowed engine's parameter instead

TOTAL_PROTOCOL_ID_COUNT

ProtocolID const Engine::TOTAL_PROTOCOL_ID_COUNT = TOTAL_PARSER_ID_COUNT

static

Last valid FIX protocol identifier.

Deprecated

Use MaximumParsersAllowed engine's parameter instead

total_storageType

const MessageStorageType Engine::total_storageType = MessageStorageType::total()

Special instance representing total number of storages for iteration.

Warning

This instance provided for backward compatibility and is deprecated. Iterate over StorageMgr registered instances instead.

transient_storageType

const MessageStorageType Engine::transient_storageType = MessageStorageType::builtin(BuiltinMessageStorage::Transient)

Memory storage - fast but dangerous.
