getNodeString

protected void getNodeString(StringBuffer str)

Overrides:

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

getDescriptionProperties

public PlanNode getDescriptionProperties()

Overrides:

getDescriptionProperties in class RelationalNode

getMode

public ProjectIntoNode.Mode getMode()

setMode

public void setMode(ProjectIntoNode.Mode mode)

isTempGroupInsert

public boolean isTempGroupInsert()

closeDirect

public void closeDirect()

Overrides:

closeDirect in class RelationalNode

getModelName

public String getModelName()

requiresTransaction

public Boolean requiresTransaction(boolean transactionalReads)

Overrides:

requiresTransaction in class RelationalNode

Returns:

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

setConstraint

public void setConstraint(Criteria constraint)

setTransactionSupport

public void setTransactionSupport(ExecutionFactory.TransactionSupport transactionSupport)

setSourceHint

public void setSourceHint(SourceHint property)

setUpsert

public void setUpsert(boolean upsert)
