Uses of Transaction in com.sleepycat.collections

Methods in com.sleepycat.collections that return Transaction
`Transaction` `CurrentTransaction.abortTransaction()` Aborts the transaction that is active for the current thread for this environment and makes the parent transaction (if any) the current transaction.
`Transaction` `CurrentTransaction.beginTransaction(TransactionConfig config)` Begins a new transaction for this environment and associates it with the current thread.
`Transaction` `CurrentTransaction.commitTransaction()` Commits the transaction that is active for the current thread for this environment and makes the parent transaction (if any) the current transaction.
`Transaction` `CurrentTransaction.getTransaction()` Returns the transaction associated with the current thread for this environment, or null if no transaction is active.
