>
> TransactionTree uses List<Integer> internally and as part of its API; this
> patch changes that and pushes the use of List<Integer> down to FPGrowth.java.
> This can be converted if the perf bug can be fixed (MAHOUT-890). I will
> also provide an alternate base FPGrowth implementation.
> Please note that this patch assumes the patch attached to MAHOUT-920 has
> already been applied.
