Python DataBus Examples

Example #1

File: test_databus.py Project: ryandoherty/RaceCapture_App

	def test_meta_listener(self):
		dataBus = DataBus()
		
		def metaListener(channel):
			self.channelMeta = channel

		metas = ChannelMetaCollection()
		metas.channel_metas = [ChannelMeta(name='RPM')]

		dataBus.addMetaListener(metaListener)
		dataBus.update_channel_meta(metas)
		dataBus.notify_listeners(None)
		self.assertEqual(self.channelMeta['RPM'], metas.channel_metas[0])

Example #2

        sample = Sample()

        meta = ChannelMeta(name='RPM')

        dataBus = DataBus()
        dataBus.addChannelListener('RPM', listener)
        dataBus.update_samples(sample)
        dataBus.notify_listeners(None)
        self.assertEqual(self.listenerVal0, 1111)

Example #3
