Method Detail

clone

public java.lang.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.

Overrides:

clone in class PlanExecutionNode

See Also:

PlanExecutionNode.clone()

reset

public void reset()

Overrides:

reset in class PlanExecutionNode

closeDirect

public void closeDirect()

Overrides:

closeDirect in class PlanExecutionNode

prepareNextCommand

protected boolean prepareNextCommand()
                              throws BlockedException,
                                     TeiidComponentException,
                                     TeiidProcessingException

Overrides:

prepareNextCommand in class PlanExecutionNode

Throws:

BlockedException

TeiidComponentException

See Also:

PlanExecutionNode.prepareNextCommand()

hasNextCommand

protected boolean hasNextCommand()

Overrides:

hasNextCommand in class PlanExecutionNode

See Also:

PlanExecutionNode.hasNextCommand()

getInputCriteria

public Criteria getInputCriteria()

Returns:

Returns the inputCriteria.

open

public void open()
          throws TeiidComponentException,
