Types

type EventAdapter

type EventAdapter interface {
	GetInterestedEvents() ([]*ehpb.Interest, error)
	Recv(msg *ehpb.Event) (bool, error)
	Disconnected(err error)
}

EventAdapter is the interface by which a openchain event client registers interested events and receives messages from the openchain event Server

type EventsClient

type EventsClient struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

EventsClient holds the stream and adapter for consumer to work with

func NewEventsClient

func NewEventsClient(peerAddress string, regTimeout time.Duration, adapter EventAdapter) (*EventsClient, error)

NewEventsClient Returns a new grpc.ClientConn to the configured local PEER.

func (*EventsClient) Recv

func (ec *EventsClient) Recv() (*ehpb.Event, error)

Recv recieves next event - use when client has not called Start

func (*EventsClient) RegisterAsync

func (ec *EventsClient) RegisterAsync(ies []*ehpb.Interest) error

RegisterAsync - registers interest in a event and doesn't wait for a response

func (*EventsClient) Start

func (ec *EventsClient) Start() error

Start establishes connection with Event hub and registers interested events with it

func (*EventsClient) Stop

func (ec *EventsClient) Stop() error

Stop terminates connection with event hub

func (*EventsClient) UnregisterAsync

func (ec *EventsClient) UnregisterAsync(ies []*ehpb.Interest) error

UnregisterAsync - Unregisters interest in a event and doesn't wait for a response
