type Node added in v0.1.13 

type Node interface {
	// Method to indicate that finalize is required for this handler
	FinalizeRequired() bool

	// Setup should be called, before invoking any other methods of this handler in a single thread context
	Setup(ctx context.Context, setupContext SetupContext) error

	// Core method that should handle this node
	Handle(ctx context.Context, executionContext NodeExecutionContext) (Transition, error)

	// This method should be invoked to indicate the node needs to be aborted.
	Abort(ctx context.Context, executionContext NodeExecutionContext, reason string) error

	// This method is always called before completing the node, if FinalizeRequired returns true.
	// It is guaranteed that Handle -> (happens before) -> Finalize. Abort -> finalize may be repeated multiple times
