Method Summary

Modifier and Type	Method	Description
List<? extends SnmpCommitResult>	commit(SnmpTransaction transaction, SnmpCommitListener commitListener)	Commits the transaction to the agent.

Method Detail

commit

List<? extends SnmpCommitResult> commit(SnmpTransaction transaction,
                                        SnmpCommitListener commitListener)

Commits the transaction to the agent.

Parameters:

transaction - the transaction to commit.

commitListener - the optional listener that is immediately informed during this commit call about failures and successful committed change sets.

Returns:

the SnmpErrorStatus indicating success or failure reason of the transaction.

rollback

void rollback(SnmpTransaction transaction)

getSnmpTransaction

SnmpTransaction getSnmpTransaction(SnmpTransactionStrategy transactionStrategy)

isAtomic

boolean isAtomic(SnmpTransaction transaction)

Checks if this transaction can be committed with atomicity. As SNMP guarantees atomicity only for a single SET PDU. That is, if a transaction cannot be completed with a single SET PDU (message), this method will return false.

Parameters:

transaction - the transaction to test.

Returns:

true if this transaction can be committed by using a single SET PDU. Thus, the variables to set do not exceed the target's maximum size PDU length (including estimated SNMP message overhead).
