      Throws:
      org.pentaho.di.core.exception.KettleException

      void injectStepMetadataEntries(List<StepInjectionMetaEntry> metadata) throws org.pentaho.di.core.exception.KettleException
      Deprecated.
      Inject the metadata specified into the step metadata
      Parameters:
      metadata - the metadata to inject.
      Throws:
      org.pentaho.di.core.exception.KettleException
    • extractStepMetadataEntries

      List<StepInjectionMetaEntry> extractStepMetadataEntries() throws org.pentaho.di.core.exception.KettleException
      Deprecated.
      Extracts the step metadata in a standard fashion. Enables unit testing more easily by extracting the step metadata and then doing the re-injection into an empty step.
