Here's a simple example on how to extract the fields:

  sym = (MibValueSymbol) mib.getSymbol("appSis");
  type = (SnmpObjectType) sym.getType();
  subtype = type.getSyntax();
  access = type.getAccess();
  status = type.getStatus();
  desc = type.getDescription();

Note that the code above assumes the types of values
returned. I recommend you check with instanceof to
avoid potential run-time exceptions.

Also, the MibType value returned by getSyntax() might
be a bit tricky to understand. In the case above it
ought to be an instance of StringType with the
appropriate size constraint set. You may wish to check
for "DisplayString" in which case you'd do:

  subtype.hasReferenceTo("DisplayString")

Mibble is a MIB parser, i.e. it allows you to read the
contents of a MIB file. It does not provide support for
modifying MIB files nor does it contain an SNMP stack
(whichever you meant).

No problem.
