Package de.xima.fc.interfaces.workflow.analysis

Interface ICreateFlowGraphContext<TElement extends IWorkflowNodeTypeProviding>

Type Parameters:

TElement - The type of the node elements on which the analysis is performed. This type may be different depending on whether the analysis is performed on the backend data model WorkflowNode or the frontend view model.

public interface ICreateFlowGraphContext<TElement extends IWorkflowNodeTypeProviding>

Context provided to the node handlers during a call to createFlowGraph. Handlers may use this context to recursively analyze their children as well.
