Member Function Documentation

virtual void kagome::storage::changes_trie::ChangesTracker::onBlockAdded ( const primitives::BlockHash &  hash )

pure virtual

Supposed to be called when a block is added to the block tree.

Implemented in kagome::storage::changes_trie::StorageChangesTrackerImpl.

virtual void kagome::storage::changes_trie::ChangesTracker::onBlockExecutionStart ( primitives::BlockHash  new_parent_hash )

pure virtual

Supposed to be called when a block execution starts

Implemented in kagome::storage::changes_trie::StorageChangesTrackerImpl.

virtual void kagome::storage::changes_trie::ChangesTracker::onPut ( const common::BufferView &  key, const common::BufferView &  value, bool  new_entry  )

pure virtual

Supposed to be called when an entry is put into the tracked storage

• new_entry states whether the entry is new, or just an update of a present value

Implemented in kagome::storage::changes_trie::StorageChangesTrackerImpl.

virtual void kagome::storage::changes_trie::ChangesTracker::onRemove ( const common::BufferView &  key )

pure virtual

Supposed to be called when an entry is removed from the tracked storage

Implemented in kagome::storage::changes_trie::StorageChangesTrackerImpl.
