[SNMP4J] getting whole table from the agent

[Dawid]

Hello,
I've just tried to get the whole table from the agent using snmp4j with no 
success.
My aim is to read ipAddrTable, so I use getBulk with the starting position 
ipAddrTable.ipAddrEntry.ipAdEntAddr.
But how should I know how big is this table? If I don't know the rows 
amount, how can I set the maxRepetitions value?

How should I project this thing?
