public class DynamicTransitionEngine
extends TransitionEngine

The DynamicTransitionEngine operates on a DynamicNode and takes the next node instances returned by the node and runs returns them in a TransitionResult after doing some processing and validation on them.

                         throws Exception

Description copied from class: TransitionEngine

Tell the WorkflowEngine processing the activeNodeInstance if the node is complete and transitionFrom can be called.

Specified by:

isComplete in class TransitionEngine

Parameters:

context - for routing

Returns:

boolean

Throws:

Exception

transitionFrom

public Transition transitionFrom(RouteContext context,
                                 ProcessResult processResult)
                          throws Exception

Overrides:

transitionFrom in class TransitionEngine

Throws:

Exception

initializeNodeGraph

private void initializeNodeGraph(RouteContext context,
                                 RouteNodeInstance dynamicNodeInstance,
                                 RouteNodeInstance nodeInstance,
                                 Set<RouteNodeInstance> nodeInstances,
                                 RouteNodeInstance finalNodeInstance)
                          throws Exception

This method checks the next node returned by the user and walks the resulting node graph, filling in required data where possible. Will throw errors if there is a problem with what the implementor has returned to us. This allows them to do things like return next nodes with no attached branches, and we will go ahead and generate the branches for them, etc.

Throws:

Exception

getFinalNodeInstance

private RouteNodeInstance getFinalNodeInstance(RouteNodeInstance dynamicNodeInstance,
                                               RouteContext context)
                                        throws Exception

Throws:

Exception
