I think I'd go one step up the OO ladder and match each event code to a
class. Have every class implement a staticmethod something like
"load(stream)" (using pickle terminology), and then use a dict to dispatch.
eventTypes = { "1" : BlahEvent, "2" : BlehEvent, "3" : BelchEvent, "4" :
BlechEvent }
eventObj = eventTypes[ stream.read(1) ].load( stream )
Now transcending from plain-old-OO to Pythonic idiom, make this into a
generator:
eventTypes = { "1" : BlahEvent, "2" : BlehEvent, "3" : BelchEvent, "4" :
BlechEvent }
def eventsFromStream(stream):
while not stream.EOF:
evtTyp = stream.read(1)
yield eventTypes[evtTyp].load(stream)
and then get them all in a list using
list( eventsFromStream( stream ) )
