Types

type LockBasedTxMgr

type LockBasedTxMgr struct {
	// contains filtered or unexported fields
}

LockBasedTxMgr a simple implementation of interface `txmgmt.TxMgr`. This implementation uses a read-write lock to prevent conflicts between transaction simulation and committing

func NewLockBasedTxMgr

func NewLockBasedTxMgr(db statedb.VersionedDB) *LockBasedTxMgr

NewLockBasedTxMgr constructs a new instance of NewLockBasedTxMgr

func (*LockBasedTxMgr) Commit

func (txmgr *LockBasedTxMgr) Commit() error

Commit implements method in interface `txmgmt.TxMgr`

func (*LockBasedTxMgr) CommitLostBlock

func (txmgr *LockBasedTxMgr) CommitLostBlock(block *common.Block) error

CommitLostBlock implements method in interface kvledger.Recoverer

func (*LockBasedTxMgr) GetLastSavepoint

func (txmgr *LockBasedTxMgr) GetLastSavepoint() (*version.Height, error)

GetLastSavepoint returns the block num recorded in savepoint, returns 0 if NO savepoint is found
