Hi Leif,
Well, after a short interlude with our project work here, I was
finally able to have a look at your altprofile code.
Nice stuff. It's certainly a lot further advanced than the code
I'd written. Well done.
I've tried to get my head around your design, etc. Please tell
me if the following analysis is right:
-----------------------------------------------------------------
The profile manager maintains a list of profilable objects,
registered either automatically by the profilable component
manager, or manually via a registerProfilable() method on the
manager itself.
Each profilable exposes 0 to many profile points which maybe of
type 'value', or 'counter'.
Upon registration with the profile manager, a profilable proxy
is created which manages profile point proxies across threadsafe
and non thread safe components.
Profile point proxies let you register listener classes for
updates from the profile points themselves. The listeners can be
implementors of a lower level ProfilePointListener class, or
high level Sample classes.
The profile manager can be configured to automatically create a
set of listeners (samplers in this case) for particular profile points
on a particular profilable. Samplers configured in this way can
be accessed via the profile manager. The gui reporter essentially
iterates through the list of available samplers when building
it's menu's.
When profilables update their profile points, each listener is
informed of the update, along the lines of the observer pattern.
The profiler manager exposes an array of all profilable descriptor
objects, which in turn expose an array of all profile point
descriptor objects, which offer reporting tools a way at
accessing the profilable objects this manager manages and
registering listeners.
-----------------------------------------------------------------
Does this analysis sound right ? Is there anything I've missed ? I do
have a few comments, but I want to make sure I've understood everything
first. :-)
Cheers,
Marcus
