Method Detail

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.

Overrides:

clone in class AccessNode

See Also:

PlanExecutionNode.clone()

reset

public void reset()

Overrides:

reset in class AccessNode

closeDirect

public void closeDirect()

Overrides:

closeDirect in class AccessNode

open

public void open()
          throws TeiidComponentException,
                 TeiidProcessingException

Overrides:

open in class AccessNode

Throws:

TeiidComponentException

TeiidProcessingException

prepareNextCommand

protected boolean prepareNextCommand(Command atomicCommand)
                              throws TeiidComponentException,
                                     TeiidProcessingException

Overrides:

prepareNextCommand in class AccessNode

Throws:

TeiidComponentException

TeiidProcessingException

See Also:

AccessNode.prepareNextCommand(org.teiid.query.sql.lang.Command)

processCommandsIndividually

protected boolean processCommandsIndividually()

Overrides:

processCommandsIndividually in class AccessNode

hasNextCommand

protected boolean hasNextCommand()

Overrides:

hasNextCommand in class AccessNode

See Also:

PlanExecutionNode.hasNextCommand()

getInputCriteria

public Criteria getInputCriteria()

Returns:

Returns the inputCriteria.

requiresTransaction

public Boolean requiresTransaction(boolean transactionalReads)

Overrides:

requiresTransaction in class AccessNode

Returns:

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