public class Workflow
extends Object

A Workflow is an abstract representation of a set of interconnected processes. Processes, or jobs, may have dependencies upon one another, may provide each other input, and/or output, or may be completely independent of one another.
See Buyya et al. for a great description in detail of what exactly a Workflow is.
Important note: As of Apache OODT 0.4, Workflows now support both pre- and post- conditions (as opposed to just pre-conditions, as was the behavior) before. The methods getConditions() and setConditions(List) are now deprecated in favor of their getPreConditions() and setPreConditions(List) and getPostConditions() and setPostConditions(List) counterparts. The existing condition only methods have been preserved for back compat, but will go away in later versions of the class and API. Also over the next few releases, we intend to change the inner APIs to use pre and post conditions.
