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
