[SNMP4J] Re: subclassing Variable

[Jeff Ramin]

I've been looking at the javadoc some more, looking for a Variable class
that I could extend...

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?
