Constructor Detail

TransEngineAdapter

public TransEngineAdapter(org.pentaho.di.engine.api.Engine engine,
                          TransMeta transMeta)

Method Detail

setLogLevel

public void setLogLevel(org.pentaho.di.core.logging.LogLevel logLogLevel)

Description copied from class: Trans

Sets the log level.

Overrides:

setLogLevel in class Trans

Parameters:

logLogLevel - the new log level

killAll

public void killAll()

Description copied from class: Trans

Attempts to stops all running steps and subtransformations. If all steps have finished, the transformation is marked as Finished.

Overrides:

killAll in class Trans

prepareExecution

public void prepareExecution(String[] arguments)
                      throws org.pentaho.di.core.exception.KettleException

Description copied from class: Trans

Prepares the transformation for execution. This includes setting the arguments and parameters as well as preparing and tracking the steps and hops in the transformation.

Overrides:

prepareExecution in class Trans

Parameters:

arguments - the arguments to use for this transformation

Throws:

org.pentaho.di.core.exception.KettleException - in case the transformation could not be prepared (initialized)

startThreads

public void startThreads()
                  throws org.pentaho.di.core.exception.KettleException

Description copied from class: Trans

Starts the threads prepared by prepareThreads(). Before you start the threads, you can add RowListeners to them.

Overrides:

startThreads in class Trans

Throws:

org.pentaho.di.core.exception.KettleException - if there is a communication error with a remote output socket.

waitUntilFinished

public void waitUntilFinished()

Description copied from class: Trans

Waits until all RunThreads have finished.

Overrides:

waitUntilFinished in class Trans

addRowProducer

public RowProducer addRowProducer(String stepname,
                                  int copynr)
                           throws org.pentaho.di.core.exception.KettleException

Description copied from class: Trans

This adds a row producer to the transformation that just got set up. It is preferable to run this BEFORE execute() but after prepareExecution()

Overrides:

addRowProducer in class Trans

Parameters:

stepname - The step to produce rows for

copynr - The copynr of the step to produce row for (normally 0 unless you have multiple copies running)

Returns:

the row producer

Throws:

org.pentaho.di.core.exception.KettleException - in case the thread/step to produce rows for could not be found.
