U - Controller class of the MVC view that is defined in this context

public class ViewContext<U>
extends AbstractContext

The view context is the context with a life time of one view. For each view there is exactly one ViewContext. By using the ViewFactory to create MVC views a ViewContext will be automatically created.
Example:

 
 ViewContext<MyController> context =
 ViewFactory.getInstance().createByController(MyController.class);

 
 

How to use a context
A context has a defined life time and can hold the data model of your application 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.

ViewContext

public ViewContext(javafx.scene.Node rootNode,
                   U controller,
                   ViewMetadata metadata,
                   ViewConfiguration configuration,
                   java.lang.Object... resources)

Create a new ViewContext for a (view-)Node and a controller. Normally this constructor is used by the ViewFactory and should not be used in application code.

??:

rootNode - the (view-)node

controller - the controller

metadata -

configuration -

resources -

??????

getResolver

public ContextResolver<U> getResolver()

getController

public U getController()

Returns the controller of the MVC view that is wrapped by this context.

??:

the controller

getRootNode

public javafx.scene.Node getRootNode()

Returns the JavaFX view node of the MVC view that is wrapped by this context.

??:

the view node

getApplicationContext

public ApplicationContext getApplicationContext()

Returns the global application context

??:

application context

destroy

public void destroy()
             throws java.lang.IllegalAccessException,
                    java.lang.IllegalArgumentException,
                    java.lang.reflect.InvocationTargetException

Destroyes the context. This will be called by the flow API if a view is closed. Normally an application should never call this.

??:

java.lang.IllegalAccessException - if the context can't be destroyed

java.lang.IllegalArgumentException - if the context can't be destroyed

java.lang.reflect.InvocationTargetException - if the context can't be destroyed

addContextDestroyedListener

public void addContextDestroyedListener(ContextDestroyedListener<U> listener)

public void removeContextDestroyedListener(ContextDestroyedListener<U> listener)
