Types

type Provider

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

Provider implements interface ledger.PeerLedgerProvider

func NewProvider

func NewProvider(initializer *ledger.Initializer) (pr *Provider, e error)

NewProvider instantiates a new Provider. This is not thread-safe and assumed to be synchronized by the caller

func (*Provider) Close

func (p *Provider) Close()

Close implements the corresponding method from interface ledger.PeerLedgerProvider

func (*Provider) Create

func (p *Provider) Create(genesisBlock *common.Block) (ledger.PeerLedger, error)

Create implements the corresponding method from interface ledger.PeerLedgerProvider This functions sets a under construction flag before doing any thing related to ledger creation and upon a successful ledger creation with the committed genesis block, removes the flag and add entry into created ledgers list (atomically). If a crash happens in between, the 'recoverUnderConstructionLedger' function is invoked before declaring the provider to be usable

func (*Provider) Exists

func (p *Provider) Exists(ledgerID string) (bool, error)

Exists implements the corresponding method from interface ledger.PeerLedgerProvider

func (*Provider) List

func (p *Provider) List() ([]string, error)

List implements the corresponding method from interface ledger.PeerLedgerProvider

func (*Provider) Open
