Hyunsik Choi commented on TAJO-267:
-----------------------------------
deepEquals() is implemented in all nodes, including ExceptNode, GroupbyNode,
IntersectNode, and so on. I think that it would be better to implement
deepEquals() is only in BinaryNode and UnaryNode. And, it may be enough that
other node types only have equals() method.
> Implement equals() and deepEquals() functions at LogicalNode
