Description

After the generated JAXB objects and after we have an understanding how Dozer works, the task is:

• implement a fluent API that covers an easy-to-use workflow creation mechanism
• similar to the one Apache Airflow uses
• WorkflowApp instances are created
• these are converted to JAXB Object s via Dozer
• these can be serialized to XML and written to filesystem
• cross checks are not yet covered
• only workflows are covered
• schema versions of workflows are not yet covered
• only the direction API -> WorkflowApp -> JAXB Object -> XML is covered
• automatical insertion of fork / join pairs is not yet covered
• automatical generation of kill nodes is not yet covered
• automatical generation of decision nodes is not yet covered
