[Mibble-users] question about syntax

[wshang]

hi,
I have been away for some days, remember me ?
I have a question about syntax.
SNMPv1,v2 use the syntax : Integer,Unsigned32,Counter32, Counter64, 
Gauge32,TimeTicks, Octect String, IpAddress ,Object Identifier ,Opaque.

when I want to know a Symbol's syntax ,I use the follow sentence:
     if (((SnmpObjectType)type).getSyntax() instanceof XXXType){ 
      //do something...
     }
but I find XXXType is only follow:
    BitSetType
    BooleanType
    ChoiceType
    IntegerType
    NullType
    ObjectIdentifierType
    SequenceOfType
    SequenceType
    StringType
there are some difference of the XXXType and the syntax the snmp use . 
for example, how can I check if a symbol is Counter64 type ?
