Types

type Query

type Query interface {
	LatestBlock(context.Context, common.Namespace) (*block.Block, error)
	GenesisBlock(context.Context, common.Namespace) (*block.Block, error)
	RuntimeState(context.Context, common.Namespace) (*roothash.RuntimeState, error)
	LastRoundResults(context.Context, common.Namespace) (*roothash.RoundResults, error)
	IncomingMessageQueueMeta(context.Context, common.Namespace) (*message.IncomingMessageQueueMeta, error)
	IncomingMessageQueue(ctx context.Context, id common.Namespace, offset uint64, limit uint32) ([]*message.IncomingMessage, error)
	Genesis(context.Context) (*roothash.Genesis, error)
	ConsensusParameters(context.Context) (*roothash.ConsensusParameters, error)
}

Query is the roothash query interface.

type QueryFactory

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

QueryFactory is the roothash query factory.

func NewQueryFactory

func NewQueryFactory(state abciAPI.ApplicationQueryState) *QueryFactory

NewQueryFactory returns a new QueryFactory backed by the given state instance.

func (*QueryFactory) QueryAt

func (sf *QueryFactory) QueryAt(ctx context.Context, height int64) (Query, error)

QueryAt returns the roothash query interface for a specific height.
