Public Functions Documentation¶

function KeyValueBlockHeaderRepository¶

KeyValueBlockHeaderRepository(
    std::shared_ptr< crdt::GlobalDB > db,
    std::shared_ptr< crypto::Hasher > hasher,
    const std::string & net_id
)

function ~KeyValueBlockHeaderRepository¶

~KeyValueBlockHeaderRepository() override =default

function getNumberByHash¶

virtual outcome::result< primitives::BlockNumber > getNumberByHash(
    const base::Hash256 & hash
) const override

Parameters:

hash - a blake2_256 hash of an SCALE encoded block header

Return: the number of the block with the provided hash in case one is in the storage or an error

Reimplements: sgns::blockchain::BlockHeaderRepository::getNumberByHash

function getHashByNumber¶

virtual outcome::result< base::Hash256 > getHashByNumber(
    const primitives::BlockNumber & number
) const override

Parameters:

number - the number of a block, contained in a block header

Return: the hash of the block with the provided number in case one is in the storage or an error

Reimplements: sgns::blockchain::BlockHeaderRepository::getHashByNumber

function getBlockHeader¶

virtual outcome::result< primitives::BlockHeader > getBlockHeader(
    const primitives::BlockId & id
) const override

Return: block header with corresponding id or an error

Reimplements: sgns::blockchain::BlockHeaderRepository::getBlockHeader

function putBlockHeader¶

virtual outcome::result< primitives::BlockHash > putBlockHeader(
    const primitives::BlockHeader & header
) override

Reimplements: sgns::blockchain::BlockHeaderRepository::putBlockHeader

function removeBlockHeader¶

virtual outcome::result< void > removeBlockHeader(
    const primitives::BlockId & id
) override

Reimplements: sgns::blockchain::BlockHeaderRepository::removeBlockHeader

function getBlockStatus¶

virtual outcome::result< blockchain::BlockStatus > getBlockStatus(
    const primitives::BlockId & id
) const override

Parameters:

id of a block which status is returned

Return: status of a block or a storage error

Reimplements: sgns::blockchain::BlockHeaderRepository::getBlockStatus

function GetName¶

inline virtual std::string GetName() override

Reimplements: IComponent::GetName

function GetHeaderPath¶

std::string GetHeaderPath() const

function GetHeaderSerializedData¶

static std::vector< uint8_t > GetHeaderSerializedData(
