[SNMP4J] Validators generated by agentpp

[Frank Fock]

Hi Rick,

Since you have confirmed to use the latest version
of AgenPro I understand that this might be a simple
misunderstanding:

As you can see from the Snmp4jHeartbeatMib example,
the validation listeners created by AgenPro are now
instances of ValueConstraint which can be adapted
as MOValueValidationListener through
ValueConstraintValidator:

   ValueConstraint snmp4jAgentHBCtrlStorageTypeVC =
     new EnumerationConstraint(
         new int[] {Snmp4jAgentHBCtrlStorageTypeEnum.other,
         Snmp4jAgentHBCtrlStorageTypeEnum._volatile,
         Snmp4jAgentHBCtrlStorageTypeEnum.nonVolatile,
         Snmp4jAgentHBCtrlStorageTypeEnum.permanent,
         Snmp4jAgentHBCtrlStorageTypeEnum.readOnly});
   ((MOMutableColumn)
    snmp4jAgentHBCtrlEntryColumns[idxSnmp4jAgentHBCtrlStorageType]).
       addMOValueValidationListener(new
         ValueConstraintValidator(snmp4jAgentHBCtrlStorageTypeVC));

Each MO instance can have more than one validation
listener. When AgenPro generates an additional value
validation listener for your custom validation, then this
listener is registered after the value range listener.

If you need to change, for example, the enumeration
validation then you can either remove the generated listener
and replace it by your custom checking or you can define
an AGENT-CAPABILITIES module and modify WRITE-SYNTAX of
the object to reflect your needs (for example "not all
enums of the original MIB definition should be supported").

Best regards,
Frank
