Types ¶
type BlockStore ¶
type BlockStore interface { AddBlock(block *common.Block) error GetBlockchainInfo() (*common.BlockchainInfo, error) RetrieveBlocks(startNum uint64) (ledger.ResultsIterator, error) RetrieveBlockByHash(blockHash []byte) (*common.Block, error) RetrieveBlockByNumber(blockNum uint64) (*common.Block, error) // blockNum of math.MaxUint64 will return last block RetrieveTxByID(txID string) (*common.Envelope, error) RetrieveTxByBlockNumTranNum(blockNum uint64, tranNum uint64) (*common.Envelope, error) RetrieveBlockByTxID(txID string) (*common.Block, error) RetrieveTxValidationCodeByTxID(txID string) (peer.TxValidationCode, error) Shutdown() }
BlockStore - an interface for persisting and retrieving blocks An implementation of this interface is expected to take an argument of type `IndexConfig` which configures the block store on what items should be indexed 区块索引的概括
type BlockStoreProvider ¶
type BlockStoreProvider interface { CreateBlockStore(ledgerid string) (BlockStore, error) OpenBlockStore(ledgerid string) (BlockStore, error) Exists(ledgerid string) (bool, error) List() ([]string, error) Close() }
BlockStoreProvider provides an handle to a BlockStore
type IndexConfig ¶
type IndexConfig struct {
AttrsToIndex []IndexableAttr
}
IndexConfig - a configuration that includes a list of attributes that should be indexed
