Method Detail

getNewInstance

public ILayoutComposer getNewInstance()
returns a new instance of the implementing class. This method is used by the LayoutControllerFactory. The Factory holds one instance of the implementing class and calls its getNewInstance method. This allows the implementing class to set parameters at the newly created instance. It also reduces calls of the Class.forName() to gain performance.
Returns:
a new instance of the implementing class, never returns null.

render

public com.sapportals.htmlb.Component render()
                                      throws WcmException
creates and returns the visible components for the user. It is called, when the control that holds this instance (usually the IProxy is rendered by the Wdf-Framework. See the Wdf-Framework for details.
Returns:
an htmlb-Component that is to be displayed to the user

getRenderer

public ILayoutObject[] getRenderer()
returns all conrols that have to be registered with the Wdf-Framework. If a control within the ILayoutController is not returned via this method, it can not use the Wdf-functionalities such as persistence of simple data types or the use of the WdfEventDispatcher to create Link or Button elements.
Returns:
an array of all controls inside the layoutcontroller that are to be registered with the WDF. The array must not contain null.

public IResourceListProvider[] getResourceListProvider()
