Types

type EventListener

type EventListener interface {
	// Register registers for a chaincode event
	Register(eventID string) error
	// BlockWait Block and wait for a chaincode event matching the previously registered eventID
	// Return cc event URL if event is received before timing out
	BlockWait(timeoutSeconds int, numMessages int) string
	// Close closes the listener and releases any assoicated resources
	Close()
}

EventListener is a chaincode event handler

type EventListenerImpl

type EventListenerImpl struct {
	ChannelID   string
	ChaincodeID string

	// an optional extra delay to apply before unblocking
	// upon receipt of event notification
	// a small time gap before returning notification so that
	// data will be available at more peers already by the time notitfication is received
	NotificationDelayMilliseconds int
	// contains filtered or unexported fields
}
