Python getSongAttrib Examples

Example #1

File: Song.py Project: wzugang/music-player

	def getFast(self, attrib, accuracy=1.0):
		# self.__getattr__ is wrapped and calls getFast().
		# Thus, access self.__dict__ directly.
		# First, check local self.__dict__ cache.
		if accuracy <= self.LocalAttribAccuracy and attrib in self.__dict__:
			return self.__dict__[attrib], self.LocalAttribAccuracy
		# Now try the DB.
		import songdb
		expectedType = getattr(songdb.Attribs.get(attrib, None), "type", None)
		if attrib in songdb.Attribs and self._useDb and self.id:
			try:
				value = songdb.getSongAttrib(self, attrib)
				value = utils.fixValue(value, expectedType)
			except AttributeError: pass
			else:
				# Cache it locally.
				object.__setattr__(self, attrib, value)
				# We expect perfect accuracy if we have it in the DB.
				return value, 1
		# All has failed so far. Try the estimate function.
		estimateFunc = getattr(self, "_estimate_" + attrib, None)
		if estimateFunc:
			value, estAccuracy = estimateFunc()
			value = utils.fixValue(value, expectedType)
			if estAccuracy == 1:
				# save locally and in DB
				setattr(self, attrib, value)
			if estAccuracy >= accuracy:
				return value, estAccuracy
