How can I...?

Example 5: An introspecting version of Examples 2/3. This creates a simple streaming system, and looks inside to see what components are running/active, and passes the resulting information over a network connection to an Axon Visualisation server. Components used: SimpleServer, TCPClient, ReadFileAdaptor, VorbisDecode, AOAudioPlaybackAdaptor, Introspector


    from Kamaelia.SimpleServerComponent import SimpleServer
    from Kamaelia.Internet.TCPClient import TCPClient
    from Kamaelia.vorbisDecodeComponent import VorbisDecode, AOAudioPlaybackAdaptor
    from Kamaelia.Util.PipelineComponent import pipeline
    import Kamaelia.ReadFileAdaptor
    # This next line is new
    from Kamaelia.Util.Introspector import Introspector

    file_to_stream = "/usr/share/wesnoth/music/wesnoth-1.ogg"
    clientServerTestPort = 1501

    def AdHocFileProtocolHandler(filename):
    class klass(Kamaelia.ReadFileAdaptor.ReadFileAdaptor):
    def __init__(self,*argv,**argd):
    super(klass,self).__init__(filename, readmode="bitrate", bitrate=400000)
    return klass

    # Start the server

    # Start the client

    # This next pipeline is new
    # Start the introspector and connect to a local visualiser
    TCPClient("", 1500),
