Examples of org.nasutekds.server.core.WorkflowImpl

org.nasutekds.server.core.WorkflowImpl
This class implements the workflow interface. Each task in the workflow is implemented by a WorkflowElement. All the tasks in the workflow are structured in a tree of tasks and the root node of the task tree is stored in the Workflow class itself. To execute a workflow, one just need to call the execute method on the root node of the task tree. Then each task in turn will execute its subordinate nodes and synchronizes them as needed.
