clone

public ProcessorPlan clone()

Description copied from class: ProcessorPlan

Return a safe clone of the ProcessorPlan. A ProcessorPlan may only be safely cloned in between processings. That is, it is only safe to clone a plan before it is opened or after it is closed.

Specified by:

clone in class ProcessorPlan

Returns:

safe clone of this ProcessorPlan, as long as it is not open for processing

close

public void close()
           throws TeiidComponentException

Description copied from class: ProcessorPlan

Close the plan after processing.

Specified by:

close in interface BatchCollector.BatchProducer

Specified by:

close in class ProcessorPlan

Throws:

TeiidComponentException

getOutputElements

public List getOutputElements()

Description copied from class: ProcessorPlan

Get list of resolved elements describing output columns for this plan.

Specified by:

getOutputElements in interface BatchCollector.BatchProducer

Specified by:

getOutputElements in class ProcessorPlan

Returns:

List of SingleElementSymbol

initialize

public void initialize(CommandContext context,
                       ProcessorDataManager dataMgr,
                       BufferManager bufferMgr)

Description copied from class: ProcessorPlan

Initialize the plan with some required pieces of data for making queries. The data manager is used to make queries and the processorID must be passed with the request so the data manager can find the processor again.

Overrides:

initialize in class ProcessorPlan

Parameters:

context - Process execution context

dataMgr - Data manager reference

bufferMgr - Buffer manager reference

nextBatch

public TupleBatch nextBatch()
                     throws BlockedException,
                            TeiidComponentException,
                            TeiidProcessingException

Description copied from class: ProcessorPlan

Get a batch of results or possibly an Exception.

Specified by:

nextBatch in interface BatchCollector.BatchProducer

Specified by:

nextBatch in class ProcessorPlan

Returns:

Batch of results

Throws:

BlockedException - indicating next batch is not available yet

TeiidComponentException - for non-business rule exception

TeiidProcessingException - for business rule exception, related to user input or modeling

open

public void open()
          throws TeiidComponentException,
                 TeiidProcessingException

Description copied from class: ProcessorPlan

Open the plan for processing.

Specified by:

open in class ProcessorPlan
