Method Detail

getLayoutModelController

<E extends LayoutNode,G extends ModifiableLayoutNode> LayoutModelController<E,G> getLayoutModelController(ContentPage aContentPage)
                                                                                                    throws CannotInstantiateControllerException

Returns a layout model controller for the specified content page. In case a layout model controller has been requested for the specified content page before, that instance is returned; otherwise a new layout model controller is returned.
Note A LayoutModelController can only be obtained for pages that either already exist or that were inserted already, i. e. the following code will fail:

 final ModifiableContentPage newPage = contentModelController.create(ContentPage.class, null)
 contentModelController.getLayoutModelController(newPage); // this will throw a CannotInstantiateControllerException
 

Instead this should be used:

 // the create call creates an unmanaged node
 final ModifiableContentPage newPage = contentModelController.create(ContentPage.class, null)
 // Insert the node to make it known to controller
 contentModelController.insert(newPage, parent, sibling);
 // Now the layout might be generated... 
 contentModelController.getLayoutModelController(newPage);
 

Parameters:

aContentPage - content page to return a layout model controller for

Returns:

the layout model controller for the specified content page; never null

Throws:

CannotInstantiateControllerException - in case a controller cannot be instantiated
