Types

type Provider

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

Provider encapusaltes two providers 1) block store provider and 2) and pvt data store provider

func NewProvider

func NewProvider() *Provider

func (*Provider) Open

func (p *Provider) Open(ledgerid string) (*Store, error)

type Store

type Store struct {
	blkstorage.BlockStore
	// contains filtered or unexported fields
}

Store encapsulates two stores 1) block store and pvt data store

func (*Store) CommitWithPvtData

func (s *Store) CommitWithPvtData(blockAndPvtdata *ledger.BlockAndPvtData) error

CommitWithPvtData commits the block and the corresponding pvt data in an atomic operation

func (*Store) GetPvtDataAndBlockByNum

func (s *Store) GetPvtDataAndBlockByNum(blockNum uint64, filter ledger.PvtNsCollFilter) (*ledger.BlockAndPvtData, error)

GetPvtDataAndBlockByNum returns the block and the corresponding pvt data. The pvt data is filtered by the list of 'collections' supplied

func (*Store) GetPvtDataByNum

func (s *Store) GetPvtDataByNum(blockNum uint64, filter ledger.PvtNsCollFilter) ([]*ledger.TxPvtData, error)

GetPvtDataByNum returns only the pvt data corresponding to the given block number The pvt data is filtered by the list of 'ns/collections' supplied in the filter A nil filter does not filter any results
