public class ViewFlowContext
extends AbstractContext

The flow context is the context for a defined flow. A flow is a linked map of different views. By using the context you can easily share your datamodel in all views of a flow.

How to use a context
A context has a defined life time and can hold the data model of your aplication or of a part of your application. To do so you can easily register objects to your context:

DataModel model = ...
context.register(model);

In your controller:
DataModel model = context.getRegisteredObject(DataModel.class);

If you need more than one instance of a class in your context you can simple register the by using string based keys:

DataModel model1 = ...
DataModel model2 = ...
context.register("firstModel", model);
context.register("secondModel", model);

In your controller:
DataModel firstModel = context.getRegisteredObject("firstModel");

A context can simple used in a controller by injecting the context. DataFX provides annotations to inject all different context types:

"@FXMLApplicationContext"
ApplicationContext myApplicationContext;

By doing so you can easily access all your data in your controller and share data between different controllers.
