Adding analyzers from existing PDI plug-ins (non-OSGi)

You can add analyzers from existing PDI non-OSGi plug-ins. For examples of custom analyzers and external resource consumers, see GitHub - pentaho/pentaho-metaverse for details.

When adding analyzers, you still need to add a compile-time dependency to the pentaho-metaverse-api JAR file and you must also create your StepAnalyzer class.

The lifecycle listener is a new plug-in:

import org.pentaho.di.core.annotations.LifecyclePlugin;
import org.pentaho.di.core.lifecycle.LifeEventHandler;
import org.pentaho.di.core.lifecycle.LifecycleListener;
import org.pentaho.platform.engine.core.system.PentahoSystem;
@LifecyclePlugin( id = "CsvFileInputPlugin", name = "CsvFileInputPlugin" )
public class CsvFileInputLifecycleListener implements LifecycleListener {
  CsvFileInputStepAnalyzer analyzer;
  CsvFileInputExternalResourceConsumer consumer;
  @Override public void onStart( LifeEventHandler lifeEventHandler ) {
    // instantiate a new analyzer
    analyzer = new CsvFileInputStepAnalyzer();
    // construct the external resource consumer for the files that it reads from
    consumer = new CsvFileInputExternalResourceConsumer();
    analyzer.setExternalResourceConsumer( consumer );
    // register the analyzer with PentahoSystem. this also adds it to the service reference list that contains ALL IStepAnalyzers registered
    PentahoSystem.registerObject( analyzer );
    // register the consumer with PentahoSystem. this also adds it to the service reference list that contains ALL IStepExternalResourceConsumers registered
    PentahoSystem.registerObject( consumer );
  }
  @Override public void onExit( LifeEventHandler lifeEventHandler ) {
  }
}
