Hi,
I've created a new "PAR" chassis component. To give an idea of it's usage,
this:
Pipeline(
PAR(
Button(caption="Next", msg="NEXT", position=(72,8)),
Button(caption="Previous", msg="PREV", position=(8,8)),
Button(caption="First", msg="FIRST" ,position=(256,8)),
Button(caption="Last", msg="LAST", position=(320,8)),
),
Chooser(items = files),
Image(size=(800,600), position=(8,48)),
).run()
Is equivalent to this:
Graphline(
CHOOSER = Chooser(items = files),
IMAGE = Image(size=(800,600), position=(8,48)),
NEXT = Button(caption="Next", msg="NEXT", position=(72,8)),
PREVIOUS = Button(caption="Previous", msg="PREV",position=(8,8)),
FIRST = Button(caption="First", msg="FIRST",position=(256,8)),
LAST = Button(caption="Last", msg="LAST",position=(320,8)),
linkages = {
("NEXT","outbox") : ("CHOOSER","inbox"),
("PREVIOUS","outbox") : ("CHOOSER","inbox"),
("FIRST","outbox") : ("CHOOSER","inbox"),
("LAST","outbox") : ("CHOOSER","inbox"),
("CHOOSER","outbox") : ("IMAGE","inbox"),
}
).run()
It's not "done" yet, but thought it worth sharing.
Regarding TODO's, I'm planning on adding a "policy" argument that allows you
to control what happens to inbound messages. Options for inbound messages
include splitting, load balancing and pooling. There's probably other
policies too.
For the curious, the code currently sits here:
http://code.google.com/p/kamaelia/source/browse/branches/private_MPS_PAR/Kamaelia/Kamaelia/Chassis/PAR.py
Incidentally, the name "PAR" is inspired by Occam's "PAR" control structure,
indicating that the things inside run in parallel with each other.
Any comments or suggestions welcome.
Regards,
Michael.
