clone

public Object clone()

Description copied from class: RelationalNode

All the implementation of Cloneable interface need to implement clone() method. The plan is only clonable in the pre-execution stage, not the execution state (things like program state, result sets, etc). It's only safe to call that method in between query processings, in other words, it's only safe to call clone() on a plan after nextTuple() returns null, meaning the plan has finished processing.

clone in class RelationalNode
