get()

std::optional< std::string > loggingapp::CommittedRecords::get ( size_t  id )

inline

get_current_txid()

ccf::TxID loggingapp::CommittedRecords::get_current_txid ( )

inline

handle_committed_transaction()

void loggingapp::CommittedRecords::handle_committed_transaction ( const ccf::TxID &  tx_id, const ccf::kv::ReadOnlyStorePtr &  store  )

inlineoverridevirtual

Receives every committed transaction, in-order, shortly after commit.

The given store contains only the changes that occured in the current transaction.

Implements ccf::indexing::Strategy.

next_requested()

std::optional< ccf::SeqNo > loggingapp::CommittedRecords::next_requested ( )

inlineoverridevirtual

Returns next tx for which this index should be populated, or nullopt if it wants none. Allows indexes to be populated lazily on-demand, or out-of-order, or reset

Implements ccf::indexing::Strategy.
