Public Functions Documentation¶

function StorageChangesTrackerImpl¶

StorageChangesTrackerImpl(
    std::shared_ptr< storage::trie::SuperGeniusTrieFactory > trie_factory,
    std::shared_ptr< storage::trie::Codec > codec,
    SubscriptionEnginePtr subscription_engine
)

function ~StorageChangesTrackerImpl¶

~StorageChangesTrackerImpl() override =default

Functor that returns the current extrinsic index, which is supposed to be stored in the state trie

function setExtrinsicIdxGetter¶

virtual void setExtrinsicIdxGetter(
    GetExtrinsicIndexDelegate f
) override

Parameters:

f is a functor that returns the current extrinsic index

Reimplements: sgns::storage::changes_trie::ChangesTracker::setExtrinsicIdxGetter

function onBlockChange¶

virtual outcome::result< void > onBlockChange(
    primitives::BlockHash new_parent_hash,
    primitives::BlockNumber new_parent_number
) override

Reimplements: sgns::storage::changes_trie::ChangesTracker::onBlockChange

Supposed to be called when the processed block changes

function onPut¶

virtual outcome::result< void > onPut(
    const base::Buffer & key,
    const base::Buffer & value,
    bool new_entry
) override

Reimplements: sgns::storage::changes_trie::ChangesTracker::onPut

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

function onRemove¶

virtual outcome::result< void > onRemove(
    const base::Buffer & key
) override

Reimplements: sgns::storage::changes_trie::ChangesTracker::onRemove

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

function constructChangesTrie¶

virtual outcome::result< base::Hash256 > constructChangesTrie(
    const primitives::BlockHash & parent,
    const ChangesTrieConfig & conf
) override

Reimplements: sgns::storage::changes_trie::ChangesTracker::constructChangesTrie

Sinks accumulated changes for the latest registered block to the changes trie and returns its root hash

function GetName¶

inline virtual std::string GetName() override

Reimplements: IComponent::GetName
