PrecedingRule Class

SourceCode.Workflow.Authoring Namespace : PrecedingRule Class

The rule is used to indicate if an Activity can start. If you want to delay the start of an Activity, not by a specified amount of Minutes, Hours or Days, but until certain conditions are met, you will define a Preceding Rule. Stated in another way, the Preceding Rule dictates under what conditions a new Activity Instance can be created. If the Preceding Rule evaluates to False, none of the other Activity Rules will be evaluated and an Instance of the Activity will not be created.
