Re: Re: Developing Embedded xAP Devices

Just dashing out but very quickly...

Not all xAP embedded devices implement full wildcarding for their
message reception (target=)  eg the Barix Barionet cheats a little.  It
has preset matches that it checks against for the wildcards and this
covers most eventualities.

If nothing else you should recognise
(assuming you use a three segment  main address and a single segment sub
address)

target=*.*.*
target=>
target=*.*.>

and for your sub addresses (assuming a single level) you should recognise

:>
:*

eg

target=>:>
target=acme.device.instance:*
Recognising when some '*'s are substituted for the segment name is
useful too - even if it's with preset matches.


BTW - although not very flexible, you can also implement wildcarding by
back substituting the '*' s in the target address with the appropriate
segment name in your address, and then matching against a  fixed string
- if that's easier.  You still need to handle '>' though
