Re: [Mibble-users] retrieving names of fields in NOTIFICATION-TYPE (traps)

[Per Cederberg]

Hi Matthew,

Doing what you want to do is unfortunately a little bit
tricky with the current Mibble API. But luckily it has
been done before, so there is code to look at. Check out
MibWriter.printType(SnmpNotificationType, String) and
MibWriter.printReferenceEntry(Object).

Basically what you need to do is to iterate over all the
Mib value symbols, finding the ones with a type of
SnmpNotificationType, and then processing the list
returned from SnmpNotificationType.getObjects(). Each
entry in that list should be an ObjectIdentifierValue
(depends on your MIB actually), from which you get the
actual symbol name with oidValue.getSymbol().getName().

Hope this helps!
