Protected Attributes

logger::LoggerPtr log_

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.

virtual iroha::MstStorage::~MstStorage ( )
iroha::MstStorage::MstStorage ( logger::LoggerPtr  log)

Constructor provide initialization of protected fields, such as logger.

Member Function Documentation

StateUpdateResult iroha::MstStorage::apply ( const shared_model::crypto::PublicKey target_peer_key,
const MstState new_state 

Apply new state for peer

target_peer_key- key for for updating state
new_state- state with new data
State with completed or updated batches General note: implementation of method covered by lock
bool iroha::MstStorage::batchInStorage ( const DataType batch) const

Check, if passed batch is in the storage

batchto be checked
true, if batch is already in the storage, false otherwise
MstState iroha::MstStorage::extractExpiredTransactions ( const TimeType current_time)

Remove expired transactions and return them

State with expired transactions General note: implementation of method covered by lock
MstState iroha::MstStorage::getDiffState ( const shared_model::crypto::PublicKey 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.

difference between own and target state General note: implementation of method covered by lock
StateUpdateResult iroha::MstStorage::updateOwnState ( const DataType tx)

Provide updating state of current peer with new transaction

tx- new transaction for insertion in state
completed and updated mst states General note: implementation of method covered by lock
MstState iroha::MstStorage::whatsNew ( ConstRefState  new_state) const

Return diff between own and new state

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