Detailed Description

Provides batch updating of an unconfirmed transactions cache.

Member Typedef Documentation

◆ Throttle

using catapult::chain::UtUpdater::Throttle = predicate<const model::TransactionInfo&, const ThrottleContext&>

Function signature for throttling cache additions.

Member Enumeration Documentation

◆ TransactionSource

enum catapult::chain::UtUpdater::TransactionSource

strong

Sources of transactions that can be updated.

Enumerator
New	A new transaction that is added for the first time.
Reverted	A previously committed transaction that was reverted.
Existing	An existing transaction that is reapplied.

Constructor & Destructor Documentation

◆ UtUpdater()

catapult::chain::UtUpdater::UtUpdater	(	cache::UtCache &	transactionsCache,
		const cache::CatapultCache &	confirmedCatapultCache,
		BlockFeeMultiplier	minFeeMultiplier,
		const ExecutionConfiguration &	executionConfig,
		const TimeSupplier &	timeSupplier,
		const FailedTransactionSink &	failedTransactionSink,
		const Throttle &	throttle
	)

Creates an updater around transactionsCache with execution configuration (executionConfig), current time supplier (timeSupplier) and failed transaction sink (failedTransactionSink). confirmedCatapultCache is the real (confirmed) catapult cache. throttle allows throttling (rejection) of transactions. minFeeMultiplier is the minimum fee multiplier of transactions allowed in the cache.

◆ ~UtUpdater()

catapult::chain::UtUpdater::~UtUpdater ( )

default

Destroys the updater.

Member Function Documentation

◆ update() [1/2]

void catapult::chain::UtUpdater::update ( const std::vector< model::TransactionInfo > & utInfos )

Updates this cache by applying new transaction infos in utInfos.

◆ update() [2/2]

void catapult::chain::UtUpdater::update	(	const utils::HashPointerSet &	confirmedTransactionHashes,
		const std::vector< model::TransactionInfo > &	utInfos
	)

Updates this cache by applying new transaction infos in utInfos and removing transactions with hashes in confirmedTransactionHashes.
