Examples of org.apache.oodt.cas.workflow.engine.WorkflowProcessor

org.apache.oodt.cas.workflow.engine.WorkflowProcessor
The new Apache OODT workflow style of processor. These processors are responsible for returning the set of underlying tasks, or conditions that can run. A sequential version will return only a single sub-processor (condition or task, or even workflow); a parallel version will return many sub processors to run. @since Apache OODT 0.4. @author mattmann @author bfoster
