Detailed Description

Handlers used by the block chain sync consumer.

Member Typedef Documentation

CommitStepFunc

using catapult::consumers::BlockChainSyncHandlers::CommitStepFunc = consumer<CommitOperationStep>

Prototype for commit step notification.

DifficultyCheckerFunc

using catapult::consumers::BlockChainSyncHandlers::DifficultyCheckerFunc = predicate<const std::vector<const model::Block*>&, const cache::CatapultCache&>

Prototype for checking block difficulties.

PreStateWrittenFunc

using catapult::consumers::BlockChainSyncHandlers::PreStateWrittenFunc = consumer<const cache::CatapultCacheDelta&, const state::CatapultState&, Height>

Prototype for pre state written notification.

StateChangeFunc

using catapult::consumers::BlockChainSyncHandlers::StateChangeFunc = consumer<const subscribers::StateChangeInfo&>

Prototype for state change notification.

TransactionsChangeFunc

using catapult::consumers::BlockChainSyncHandlers::TransactionsChangeFunc = consumer<const TransactionsChangeInfo&>

Prototype for transaction change notification.

UndoBlockFunc

using catapult::consumers::BlockChainSyncHandlers::UndoBlockFunc = consumer<const model::BlockElement&, observers::ObserverState&, UndoBlockType>

Prototype for undoing a block.

Note

This is called with all rolled back blocks and the (new) common block.
