An Integrity Item might contain attachments. Attachments can be extracted to files using a dedicated command:
import com.sodius.mdw.metamodel.integrity.Attachment; import com.sodius.mdw.metamodel.integrity.io.ExtractAttachmentCommand; ... com.sodius.mdw.metamodel.integrity.Attachment attachment = ...; File outputFile = ...; new ExtractAttachmentCommand(attachment, outputFile).execute();
