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.

Specified by:

clone in class RelationalNode

Since:

4.2

Object.clone()

getObjects

public Collection<? extends LanguageObject> getObjects()

Specified by:

getObjects in class SubqueryAwareRelationalNode

requiresTransaction

public Boolean requiresTransaction(boolean transactionalReads)

Overrides:

requiresTransaction in class SubqueryAwareRelationalNode

Returns:

true if required, false if not required, and null if a single source command is issued and a transaction may be needed.

getDescriptionProperties

public PlanNode getDescriptionProperties()

Overrides:

getDescriptionProperties in class RelationalNode
