func (*Store) CheckpointsFromNode ¶
CheckpointsFromNode return all checkpoints from specified block height and hash
func (*Store) GetBlockHashesByHeight ¶
GetBlockHashesByHeight return the block hash by the specified height
func (*Store) GetBlockHeader ¶
GetBlockHeader return the BlockHeader by given hash
func (*Store) GetBlockTransactions ¶
GetBlockTransactions return the Block transactions by given hash
func (*Store) GetCheckpoint ¶
func (*Store) GetCheckpointsByHeight ¶
func (s *Store) GetCheckpointsByHeight(height uint64) ([]*state.Checkpoint, error)
GetCheckpointsByHeight return all checkpoints of specified block height
func (*Store) GetMainChainHash ¶
GetMainChainHash return the block hash by the specified height
func (*Store) GetStoreStatus ¶
func (s *Store) GetStoreStatus() *state.BlockStoreState
GetStoreStatus return the BlockStoreStateJSON
func (*Store) GetTransactionsUtxo ¶
GetTransactionsUtxo will return all the utxo that related to the input txs
func (*Store) SaveBlockHeader ¶
func (s *Store) SaveBlockHeader(blockHeader *types.BlockHeader) error
SaveBlockHeader persists a new block header in the protocol.
func (*Store) SaveChainStatus ¶
func (s *Store) SaveChainStatus(blockHeader *types.BlockHeader, mainBlockHeaders []*types.BlockHeader, view *state.UtxoViewpoint, contractView *state.ContractViewpoint, finalizedHeight uint64, finalizedHash *bc.Hash) error
SaveChainStatus save the core's newest status && delete old status
