[aosd-discuss] Hyper/J vs Apect-J

[Peri Tarr]

A correction:  you are NOT limited to combining two pieces of software with
Hyper/J--you can combine any number, and different ones can "interact" in
different ways.  I'm not familiar with the MIR, so I can't speak to how the
protocol might work with Hyper/J, but it sounds interesting--can you
provide a reference?  (Apologies if I've missed one previously--I've only
just returned from several days away and my inbox is a swamp that can't be
sorted by threads...sigh...)

I would like to refer to one point only, so for the sake of simplcity I
deleted the rest of the corospondences.

MIR:  Multi-Interacion-Resolution

The issue is when, how, by whom and on what visability rules interaction
resolutions could be made. It is true that in AspectJ we have the "base"
and "aspects" that are reated differently where as in Hyper/J any two
pieces
os software can be combind with each other.
Both hyper/j (?) and AspectJ are limited to interaction of TWO pieces of
software at a time. This makes interaction resolution based on a group of
software pieces complicated.  many times there is no simple serialization
sequence of pairs-interactions that can simulate this
Multi-Interacion-Resolution

How would you simulate a general MIR- Multi-Interacion-Resolution in
AspectJ?
Hyper/j?
