I'm writing some device simulators using SNMP4J. i've got quite a few to do so wrote something to parse the mib and create some java classes and annotate the properties with the MIB info. I then wrote something to iterate through the fields and create some MOs using reflection.
My first was based on a fairly simple MIB that simply had a few nested objects and a table which is comprised of a type with simple types. I wrote a table model that wraps an array list.
My second mib has a table that has nested objects, e.g. each row has an object and those objects also have objects. I cant see how I can expose those to snmp4j, the table model getValue returns a Variable.
For example, the first one is easy just implement a table model that returns the indexed field in getValue
Table A[0]
- height
- width
The next one I don't know what to do for the instance of Object C
Table B[0]
- height
- width
- Object C
- someValue
- someOtherValue
Have you checked your MIB for correct SMIv2 syntax yet? Nested tables as you illustrated in the example Table B are not supported by SMIv1 nor SMIv2.
With SNMP and its Structure of Management Information (SMI), nested tables are realised by specifying two "flat" tables (instead of a single nested table) where the first and the second table share the same index columns but the second adds one or more additional index columns.
