I will modify it to make use of generic type. Thanks.

Review comment:
The reason why I changed Result to Object here is that this method is
used by both checkAndMutate() and mutateRow() and we need to use different
types each case (respectively CheckAndMutateResult and Result). However as you
mentioned, we can make use of generic type here. I will modify it. Thanks.

Okay. I will remove the IS annotation. Thanks.
