EngineContext
public class EngineContext implements WorkflowContext(Code)
The EngineContext exposes runtime data for a workflow instance. When a new EngineContext is created, it associates itself with the current thread, and can be retrieved from any stack frame on the same thread by calling the static EngineContext.peekContext method.
