[SNMP4J] Setting Agent managed object values

[Eugene R. Snider]

In the TestAgent and ifMIB example code how does the Agent update the 
values of a managed object? For example if I use the static creation 
example to create rows for the ethernet devices how do I update inOctets 
or outOctets from the agent side? For the MOScalar class there is a well 
defined setValue function but I can't find an equivalent function for 
cells in a row. I thought I might need to maintain a copy of the row 
locally but I can't find an update function. Would I need to remove and 
re-add the row whenever a value in one column changed?

Or is there some way to provide a callback function that the agent will 
invoke to manage the object?

Thanks,
Gene
