Abstract

Enabling creation of control flow patterns in a workflow via continuations. Each continuation represents an activity execution context for an activity executing in the workflow by a workflow engine virtualizing a managed execution environment. Responsive to a request, the activity execution context is recreated via the continuation and the activity is executed within the recreated context.
