func (*DBListen) Listen ¶

func (d *DBListen) Listen(chanName string, pos int64, fn func(p pubsub.PartialWrapper)) error

Listen blocks forever. Reconnects when the connection is lost. Call Close() to stop listening. Returns an error if fails to listen. Returns nil if closed cleanly.

	*DBNotifier
	*DBListen
	// contains filtered or unexported fields
}
