> org.apache.ignite.internal.tx.impl.HeapLockManager#locks require better

> iteration.
> {code:java}
> public Iterator<Lock> locks(UUID txId) {
> // TODO: tmp, use index instead.
> List<Lock> result = new ArrayList<>();
> for (Map.Entry<LockKey, LockState> entry : locks.entrySet()) {
> Waiter waiter = entry.getValue().waiter(txId);
> if (waiter != null) {
> result.add(
> new Lock(
> entry.getKey(),
> waiter.lockMode(),
> txId
> )
> );
> }
> }
> return result.iterator();
> }{code}
