Detailed Description

MstStorage responsible for manage own and others MstStates. All methods of storage covered by mutex, because we assume that mutex possible to execute in concurrent environment.

Member Function Documentation

apply()

StateUpdateResult iroha::MstStorage::apply	(	shared_model::interface::types::PublicKeyHexStringView	target_peer_key,
		const MstState &	new_state
	)

Apply new state for peer

Parameters

target_peer_key	- key for for updating state
new_state	- state with new data

Returns

State with completed or updated batches General note: implementation of method covered by lock

batchInStorage()

bool iroha::MstStorage::batchInStorage

(

const DataType &

batch

)

const

Check, if passed batch is in the storage

Parameters

batch

to be checked

Returns

true, if batch is already in the storage, false otherwise

extractExpiredTransactions()

MstState iroha::MstStorage::extractExpiredTransactions

(

const TimeType &

current_time

)

Remove expired transactions and return them

Returns

State with expired transactions General note: implementation of method covered by lock

getDiffState()

MstState iroha::MstStorage::getDiffState	(	shared_model::interface::types::PublicKeyHexStringView	target_peer_key,
		const TimeType &	current_time
	)

Make state based on diff of own and target states. All expired transactions will be removed from diff.

Returns

difference between own and target state General note: implementation of method covered by lock

processFinalizedTransaction()

void iroha::MstStorage::processFinalizedTransaction

(

shared_model::interface::types::HashType const &

hash

)

updateOwnState()

StateUpdateResult iroha::MstStorage::updateOwnState

(

const DataType &

tx

)

Provide updating state of current peer with new transaction

Parameters

tx	- new transaction for insertion in state

Returns

completed and updated mst states General note: implementation of method covered by lock

whatsNew()

MstState iroha::MstStorage::whatsNew

(

ConstRefState

new_state

)

const

Return diff between own and new state

Parameters

new_state

- state with new data

Returns

state that contains new data with respect to own state General note: implementation of method covered by lock
