Hi Jeff,
You can use http://www.snmp4j.org/doc/org/snmp4j/smi/VariantVariable.html
However, depending on your requirements other instrumentation
approaches may fit better. See the AgenPro
SNMP4J-Instrumentation-HowTo for more details. The PDF is part
of the AgenPro distribution ZIP (http://www.agentpp.com).
Best regards,
Frank

I've been looking at the javadoc some more, looking for a Variable class

I was hoping to see an abstract method for all Variables that could be used
for retrieving a value, but one doesn't seem to exist.
Is my only option here to create my own direct descendant of Variable,
which
would implement all abstract methods?
