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
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
