Interface IWorkflowService

public interface IWorkflowService

Provides service for OpenPages native workflow features. The native workflow feature provides the automation of a business process while information is passed from one participant to another based on procedural set of rules. Refer this document for basic concepts and terminology: http://www.aiai.ed.ac.uk/project/wfmc/ARCHIVE/DOCS/glossary/glossary.html The service provides API to: - create/fetch/update/delete process definitions - start process on a resource - process workflow transitions - fetch process/activity instances - run administrative operations on process/activity instances

Since:

8.0.0.2
